In this paper the authors mainly proved that:If the finite group G has two conjugate classes of non-subnormal subgroups H={H_1,H_2,"",H_m} and K={K_1,K_2,"",K_n},then G is soluble,and|G|has at most three prime factors,and G satisfing one of the following conditions: (1)G=H■Q,where H is a p-group which has cyclic maximal subgroups,and Q is the Sylowq-sub- group of G,p and q are different primes.
主要证明了:若有限群G只含两个非次正规子群共轭类H=(H_1,H_2,…,H_m)和K={K_1,K_2,…,K_n},则G可解。
