Abstract:
Suppose that G is a finite group and H is a subgroup of G. We say that H is s-semipermutable in G if H G p = G p H for any Sylow p-subgroup G p of G with (p, |H|) = 1. We investigate the influence of s-semipermutable subgroups on the structure of finite groups. Some recent results are generalized and unified.
Keywords:s-semipermutable subgroup   the generalized Fitting subgroup   p-nilpotent group   saturated formation
