Subgroup properties are properties of subgroups of a group. These properties are assumed to satisfy only one condition : they must be invariant up to commuting isomorphism. That is, if and are isomorphic groups, and is a subgroup of whose image under the isomorphism is then has the property in if and only if has the property in .
