WebG has composite order greater than 1 (the trivial group is automatically non-simple). Then there is a prime p such that p divides jGj, which implies by Corollary 4.3 that there is a cyclic subgroup H of order p in G. Because G does not have prime order, H is a proper subgroup of G. In fact, H is normal in G, because all subgroups of an abelian ... WebG has composite order greater than 1 (the trivial group is automatically non-simple).

WebBy Lagrange's theorem, an element of G has order 1, p, q, or pq. There is only one element of order 1. If there is an element of order pq, then G is the cyclic group generated by it. Otherwise, every non-identity element of G has order p or q, and there is at least one such element, x. Let H be the subgroup generated by x.
