Webbthe cyclic decomposition of nite abelian groups, there are three abelian groups of order p3 up to isomorphism: Z=(p3), Z=(p2) Z=(p), and Z=(p) Z=(p) Z=(p). These are nonisomorphic since they have di erent maximal orders for their elements: p3, p2, and p respectively. We will show there are two nonabelian groups of order p3 up to isomorphism. top fin silenstream 30
