Answer: a Explanation: Let p be the order of g (hence the order of G). As a contradiction, assume that p=ab is a composite number with integers a > 1, b > 1. Then (ga) is a proper normal subgroup of G. This is a contradiction since G is simple.

WebCorollary: if m divides the order of a nite Abelian group G then G has a subgroup of order m: Proof: by induction on n = jGj:If n = 1 then m = 1 and result is trivial.
