摘要
将p可解群的有关结果推广到π可解群 ,得到了π可解群的一个结构定理 .设G为π可解群 ,N为G的任意非单位正规子群 .如果商群G/N的π长不超过k,而G的π长大于k ,则G的极大正规π′子群 ,Frattini子群为单位群 ,且G有唯一的极小正规子群F(G) .
In this paper the author generalizes some results of πsoluble groups and gets a structural theorem on πsoluble groups. Let G be a πsoluble group, N any non\|identity normal subgroup of G . If l π( G/N )≤ k and l π ( G )> k , then the maximal normal π′subgroup of G and the Frattini subgroup of G are both identity subgroups and G has a unique minimal normal subgroup F(G) .
