In [[number theory]] '''Euler's criterion''' is a formula for determining whether an [[integer]] is a [[quadratic residue]] [[modular arithmetic|modulo]] a [[prime number|prime]]. Precisely,
{{For|the number of labeled trees in graph theory|Cayley's formula}}


Let ''p'' be an [[odd number|odd]] prime and ''a'' an integer [[coprime]] to ''p''. Then<ref>Gauss, DA, Art. 106</ref>
In [[group theory]], '''Cayley's theorem''', named in honor of [[Arthur Cayley]], states that every [[group (mathematics)|group]] ''G'' is [[group isomorphism|isomorphic]] to a [[subgroup]] of the [[symmetric group]] acting on ''G''.<ref>Jacobson (2009), p. 38.</ref> This can be understood as an example of the [[group action]] of ''G'' on the elements of ''G''.<ref>Jacobson (2009), p. 72, ex. 1.</ref>


:<math>
A [[permutation]] of a set ''G'' is any [[bijective]] [[function (mathematics)|function]] taking ''G'' onto ''G''; and the set of all such functions forms a group under [[function composition]], called ''the symmetric group on'' ''G'', and written as Sym(''G'').<ref>Jacobson (2009), p. 31.</ref>
a^{\tfrac{p-1}{2}} \equiv
\begin{cases}
\;\;\,1\pmod{p}& \text{ if there is an integer }x \text{ such that }a\equiv x^2 \pmod{p}\\
    -1\pmod{p}& \text{ if there is no such integer.}
\end{cases}
</math>


Euler's criterion can be concisely reformulated using the [[Legendre symbol]]:<ref>Hardy & Wright, thm. 83</ref>
Cayley's theorem puts all groups on the same footing, by considering any group (including infinite groups such as ('''''R''''',+)) as a [[permutation group]] of some underlying set. Thus, theorems which are true for permutation groups are true for groups in general.
:<math>
\left(\frac{a}{p}\right) \equiv a^{(p-1)/2} \pmod p.
</math>


The criterion first appeared in a 1748 paper by [[Leonhard Euler|Euler]].<ref>Lemmermeyer, p. 4 cites two papers, E134 and E262 in the Euler Archive</ref>

nonetheless argues that the standard name&mdash;"Cayley's Theorem"&mdash;is in fact appropriate. Cayley, in his original 1854 paper,<ref>{{Citation  | last = Cayley | first = Arthur | author-link = Arthur Cayley | title = On the theory of groups as depending on the symbolic equation θ<sup>n</sup>=1  | journal = Phil.

showed that the correspondence in the theorem is one-to-one, but he failed to explicitly show it was a homomorphism (and thus an isomorphism).  However, Nummela notes that Cayley made this result known to the mathematical community at the time, thus predating Jordan by 16 years or so.


==Proof==
== Proof of the theorem ==
Where ''g'' is any element of ''G'', consider the function ''f''<sub>''g''</sub> : ''G'' → ''G'', defined by ''f''<sub>''g''</sub>(''x'') = ''g''*''x''. By the existence of inverses, this function has a two-sided inverse, <math>f_{g^{-1}}</math>. So multiplication by ''g'' acts as a [[bijective]] function. Thus, ''f''<sub>''g''</sub> is a permutation of ''G'', and so is a member of Sym(''G'').


The proof uses fact that the residue classes modulo a prime number are a [[finite field|field]]. See the article [[Characteristic_(algebra)#Case_of_fields|prime field]] for more details. The fact that there are (''p'' − 1)/2 quadratic residues and the same number of nonresidues (mod ''p'') is proved in the article [[quadratic residue]].
The set <math>K = \{f_g: g \in G\}</math> is a subgroup of Sym(''G'') which is isomorphic to ''G''. The fastest way to establish this is to consider the function ''T'' : ''G'' → Sym(''G'') with ''T''(''g'') = ''f''<sub>''g''</sub> for every ''g'' in ''G''. ''T'' is a [[group homomorphism]] because (using "•" for composition in Sym(''G'')):


[[Fermat's little theorem]] says that
:<math> (f_g \cdot f_h)(x) = f_g(f_h(x)) = f_g(h*x) = g*(h*x) = (g*h)*x = f_{(g*h)}(x)\mbox{,}</math>
:<math>
for all ''x'' in ''G'', and hence:
a^{p-1}\equiv 1 \pmod p.
:<math> T(g) \cdot T(h) = f_g \cdot f_h = f_{(g*h)} = T(g*h).</math>
</math>
The homomorphism ''T'' is also [[injective]] since ''T''(''g'') = id<sub>''G''</sub> (the identity element of Sym(''G'')) implies that ''g*x'' = ''x'' for all ''x'' in ''G'', and taking ''x'' to be the identity element ''e'' of ''G'' yields ''g'' = ''g''*''e'' = ''e''. Alternatively, ''T'' is also [[injective]] since, if ''g''*''x''=''g'''*''x'' implies ''g''=''g' '' (by post-multiplying with the inverse of ''x'', which exists because ''G'' is a group).
This can be written as
:<math>
(a^{\tfrac{p-1}{2}}-1)(a^{\tfrac{p-1}{2}}+1)\equiv 0 \pmod p.
</math>  
Since the integers mod ''p'' form
a field, one or the other of these factors must be congruent to zero.


Now if ''a'' is a quadratic residue, ''a'' &equiv; ''x''<sup>2</sup>,
Thus ''G'' is isomorphic to the image of ''T'', which is the subgroup ''K''.
:<math>
a^{\tfrac{p-1}{2}}\equiv{x^2}^{\tfrac{p-1}{2}}\equiv x^{p-1}\equiv1\pmod p.
</math>
So every quadratic residue (mod ''p'') makes the first factor zero.


[[Lagrange's theorem (number theory)|Lagrange's theorem]] says that there can be no more than (''p''&nbsp;−&nbsp;1)/2 values of ''a'' that make the first factor zero. But it is known that there are (''p''&nbsp;−&nbsp;1)/2 distinct quadratic residues (mod ''p''). Therefore they are precisely the residue classes that make the first factor zero. The other (''p''&nbsp;−&nbsp;1)/2 residue classes, the nonresidues, must be the ones making the second factor zero. This is Euler's criterion.
''T'' is sometimes called the ''regular representation of'' ''G''.


==Examples==
=== Alternative setting of proof ===
'''Example 1: Finding primes for which ''a'' is a residue'''
An alternative setting uses the language of [[group action]]s. We consider the group <math>G</math> as a G-set, which can be shown to have permutation representation, say <math>\phi</math>.


Let ''a'' = 17. For which primes ''p'' is 17 a quadratic residue?
Firstly, suppose <math>G=G/H</math> with <math>H=\{e\}</math>. Then the group action is <math>g.e</math> by [[group action|classification of G-orbits]] (also known as the orbit-stabilizer theorem).


We can test prime ''p'''s manually given the formula above.
Now, the representation is faithful if <math>\phi</math> is injective, that is, if the kernel of <math>\phi</math> is trivial. Suppose <math>g\in\ker\phi</math> Then, <math>g=g.e=\phi(g).e</math> by the equivalence of the permutation representation and the group action. But since <math>g \in \ker\phi</math>, <math>\phi(g)=e</math> and thus <math>\ker\phi</math> is trivial. Then <math>\mathrm{Im} \phi < G</math> and thus the result follows by use of the [[first isomorphism theorem]].


In one case, testing ''p'' = 3, we have 17<sup>(3 − 1)/2</sup> = 17<sup>1</sup> ≡ 2 ≡ −1 (mod 3), therefore 17 is not a quadratic residue modulo 3.
==Remarks on the regular group representation==
The identity group element corresponds to the identity permutation. All other group elements correspond to a permutation that does not leave any element unchanged. Since this also applies for powers of a group element, lower than the order of that element, each element corresponds to a permutation which consists of cycles which are of the same length: this length is the order of that element. The elements in each cycle form a left [[coset]] of the subgroup generated by the element.


In another case, testing ''p'' = 13, we have 17<sup>(13 − 1)/2</sup> = 17<sup>6</sup> ≡ 1 (mod 13), therefore 17 is a quadratic residue modulo 13.  As confirmation, note that 17 ≡ 4 (mod 13), and 2<sup>2</sup> = 4.
==Examples of the regular group representation==
Z<sub>2</sub> = {0,1} with addition modulo 2; group element 0 corresponds to the identity permutation e, group element 1 to permutation (12).


We can do these calculations faster by using various modular arithmetic and Legendre symbol properties.
Z<sub>3</sub> = {0,1,2} with addition modulo 3; group element 0 corresponds to the identity permutation e, group element 1 to permutation (123), and group element 2 to permutation (132). E.g. 1 + 1 = 2 corresponds to (123)(123)=(132).


If we keep calculating the values, we find:
Z<sub>4</sub> = {0,1,2,3} with addition modulo 4; the elements correspond to e, (1234), (13)(24), (1432).
:(17/''p'') = +1 for ''p'' = {13, 19, ...} (17 is a quadratic residue modulo these values)


:(17/''p'') = −1 for ''p'' = {3, 5, 7, 11, 23, ...} (17 is not a quadratic residue modulo these values).
The elements of [[Klein four-group]] {e, a, b, c} correspond to e, (12)(34), (13)(24), and (14)(23).


'''Example 2: Finding residues given a prime modulus ''p'' '''
S<sub>3</sub> ([[dihedral group of order 6]]) is the group of all permutations of 3 objects, but also a permutation group of the 6 group elements:

: 7<sup>2</sup> = 49 ≡ 15 (mod 17)
: 8<sup>2</sup> = 64 ≡ 13 (mod 17).


So the set of the quadratic residues modulo 17 is {1,2,4,8,9,13,15,16}.  Note that we did not need to calculate squares for the values 9 through 16, as they are all negatives of the previously squared values (e.g. 9 ≡ −8 (mod 17), so 9<sup>2</sup> ≡ (−8)<sup>2</sup> = 64 ≡ 13 (mod 17)).

We can find quadratic residues or verify them using the above formula.  To test if 2 is a quadratic residue modulo 17, we calculate 2<sup>(17 − 1)/2</sup> = 2<sup>8</sup> ≡ 1 (mod 17), so it is a quadratic residue.  To test if 3 is a quadratic residue modulo 17, we calculate 3<sup>(17 − 1)/2</sup> = 3<sup>8</sup> ≡ 16 ≡ −1 (mod 17), so it is not a quadratic residue.

28 year-old Painting Investments Worker Truman from Regina, usually spends time with pastimes for instance interior design, property developers in new launch ec Singapore and writing. Last month just traveled to City of the Renaissance.

In group theory, Cayley's theorem, named in honor of Arthur Cayley, states that every group G is isomorphic to a subgroup of the symmetric group acting on G.[1] This can be understood as an example of the group action of G on the elements of G.[2]

A permutation of a set G is any bijective function taking G onto G; and the set of all such functions forms a group under function composition, called the symmetric group on G, and written as Sym(G).[3]

Cayley's theorem puts all groups on the same footing, by considering any group (including infinite groups such as (R,+)) as a permutation group of some underlying set. Thus, theorems which are true for permutation groups are true for groups in general.

History

Although Burnside[4] attributes the theorem to Jordan,[5] Eric Nummela[6] nonetheless argues that the standard name—"Cayley's Theorem"—is in fact appropriate. Cayley, in his original 1854 paper,[7] showed that the correspondence in the theorem is one-to-one, but he failed to explicitly show it was a homomorphism (and thus an isomorphism). However, Nummela notes that Cayley made this result known to the mathematical community at the time, thus predating Jordan by 16 years or so.

Proof of the theorem

Where g is any element of G, consider the function fg : G → G, defined by fg(x) = g*x. By the existence of inverses, this function has a two-sided inverse, . So multiplication by g acts as a bijective function. Thus, fg is a permutation of G, and so is a member of Sym(G).

The set is a subgroup of Sym(G) which is isomorphic to G. The fastest way to establish this is to consider the function T : G → Sym(G) with T(g) = fg for every g in G. T is a group homomorphism because (using "•" for composition in Sym(G)):

for all x in G, and hence:

The homomorphism T is also injective since T(g) = idG (the identity element of Sym(G)) implies that g*x = x for all x in G, and taking x to be the identity element e of G yields g = g*e = e. Alternatively, T is also injective since, if g*x=g'*x implies g=g' (by post-multiplying with the inverse of x, which exists because G is a group).

Thus G is isomorphic to the image of T, which is the subgroup K.

T is sometimes called the regular representation of G.

Alternative setting of proof

An alternative setting uses the language of group actions. We consider the group as a G-set, which can be shown to have permutation representation, say .

Firstly, suppose with . Then the group action is by classification of G-orbits (also known as the orbit-stabilizer theorem).

Now, the representation is faithful if is injective, that is, if the kernel of is trivial. Suppose Then, by the equivalence of the permutation representation and the group action. But since , and thus is trivial. Then and thus the result follows by use of the first isomorphism theorem.

Remarks on the regular group representation

The identity group element corresponds to the identity permutation. All other group elements correspond to a permutation that does not leave any element unchanged. Since this also applies for powers of a group element, lower than the order of that element, each element corresponds to a permutation which consists of cycles which are of the same length: this length is the order of that element. The elements in each cycle form a left coset of the subgroup generated by the element.

Examples of the regular group representation

Z2 = {0,1} with addition modulo 2; group element 0 corresponds to the identity permutation e, group element 1 to permutation (12).

Z3 = {0,1,2} with addition modulo 3; group element 0 corresponds to the identity permutation e, group element 1 to permutation (123), and group element 2 to permutation (132). E.g. 1 + 1 = 2 corresponds to (123)(123)=(132).

Z4 = {0,1,2,3} with addition modulo 4; the elements correspond to e, (1234), (13)(24), (1432).

The elements of Klein four-group {e, a, b, c} correspond to e, (12)(34), (13)(24), and (14)(23).

S3 (dihedral group of order 6) is the group of all permutations of 3 objects, but also a permutation group of the 6 group elements:

* e a b c d f permutation
e e a b c d f e
a a e d f b c (12)(35)(46)
b b f e d c a (13)(26)(45)
c c d f e a b (14)(25)(36)
d d c a b f e (156)(243)
f f b c a e d (165)(234)
