摘要
设p,q为奇素数,且p>q,而G是p2 q2阶群.如果G是非交换的超可解群且它的Sylowp-子群初等交换,那么:1)当q整除(p-1)但q2不整除(p-1)时,G恰有(q+4)个彼此不同构的类型;2)当q2整除(p-1)时,G恰有(q2+3q+10)/2个彼此不同构的类型.这一结果完善了已有文献对p2 q2阶有限群的分类结果.
Let p, q be odd primes such that p〉q, let G be a finite group of order p^2q^2. If G is a non-Abelian supersolvable group with elementary Abelian Sylow :0-subgroups, this paper concludes that: 1) If q divides (p-1) and q^2 doesn't divide (p-1), G has (q+4) nonisomorphic structures; 2) If q^2 divides (p-1), G has (q^2+3q+10)/2 nonisomorphic structures. This result corrects the careless omission in our paper at the early stage.
