Prove the Finite Subgroup Theorem: let G be a group and H a finite non-empty subset of G. Then H is a subgroup of G if and only if whenever g, h H, then gh € H. Furthermore, give an example where this theorem does not hold for an infinite set H in a group G (thus, that H is finite is crucial to the theorem).
