摘要
证明了有限可解群的若干性质:若有限群G的非正规非交换极大子群皆共轭,则G是可解群;若有限群G中非正规子群的共轭类个数不超过极大子群的共轭类个数,则G是可解群;设G是有限群,若G的非幂零极大子群的指数为素数或素数的平方,则G是可解群.
In this paper,some sufficient conditions on solvability of finite groups obtained:If all non-normal non-abelian subgroups of a finite group G are conjugate,then G is solvable;If the number of conjugacy classes of non-normal subgroups of a finite group G is no more than thenumber of conjugacy classes of maximal subgroups of G,then G is solvable;If the indexs of its non-nilpotent maximal subgroups of G are prime or the square of prime,then G is solvable.
