| '''65''' ('''sixty-five''') is the [[natural number]] following [[64 (number)|64]] and preceding [[66 (number)|66]]. | |
| | |
| ==In mathematics==
| |
| '''Sixty-five''' is the 23rd<ref>{{OEIS|A001358}}</ref> [[semiprime]] and the 3rd of the form (5.q)it is an [[octagonal number]]. It is also a [[Cullen number]]. Given 65, the [[Mertens function]] returns [[0 (number)|0]].
| |
| | |
| '''Sixty-five''' has an [[aliquot sum]] of 19 and is the first composite number in the 19-aliquot tree. | |
| | |
| This number is the [[magic constant]] of 5 by 5 normal [[magic square]]:

| |
| \begin{bmatrix}
| |
| 17 & 24 & 1 & 8 & 15 \\
| |
| 23 & 5 & 7 & 14 & 16 \\
| |
| 4 & 6 & 13 & 20 & 22 \\
| |
| 10 & 12 & 19 & 21 & 3 \\
| |
| 11 & 18 & 25 & 2 & 9
| |
| \end{bmatrix}.
| |
| </math>
| |
| | |
| This number is also the [[magic constant]] of [[Eight queens puzzle|n-Queens Problem]] for n = 5.<ref>{{SloanesRef|sequencenumber= A006003}}</ref>
| |
| | |
| 65 is the smallest integer that can be expressed as a sum of two distinct positive squares in two ways, 65 = 8<sup>2</sup> + 1<sup>2</sup> = 7<sup>2</sup> + 4<sup>2</sup>.
| |
| | |
| It appears in the [[Padovan sequence]], preceded by the terms 28, 37, 49 (it is the sum of the first two of these).
| |
| | |
| There are only 65 known [[Euler's idoneal numbers]].
| |
| | |
| In base 14, 65 is a [[cyclic number]].
| |
| | |
| 65=1<sup>5</sup>+2<sup>4</sup>+3<sup>3</sup>+4<sup>2</sup>+5<sup>1</sup>
| |
| | |
| 65 is the length of the hypotenuse of 4 different [[pythagorean triple|pythagorean triangles]], the lowest number to have more than 2: 65<sup>2</sup> = 16<sup>2</sup> + 63<sup>2</sup> = 33<sup>2</sup> + 56<sup>2</sup> = 39<sup>2</sup> + 52<sup>2</sup> = 25<sup>2</sup> + 60<sup>2</sup>. The first two are "primitive", and 65 is the lowest number to be the largest side of more than one such triple.
