Some criteria for the nonsimplicity of finite groups
E. M. Palchik, S. Yu. Bashun Polotsk State University, Novopolotsk
Abstract:
Let |G|=∏ni=1pαii, where pi are prime numbers, pi≠pj for i≠j. Let π(G)={p1,…,pn}, s∈π(G) and let T is the set of some Sylow subgroups of the group G, that are taken one at a time for every pi∈π(G)∖{s}, i=¯1,n−1. It is proved that if every subgroup from the set T normalises some non-identity s-subgroup from G, s>3, then G has solvable normal subgroup R and s divide |R|.
Keywords:
finite group, Sylow subgroup, s-solvable group.
