Finite group with given c-permutable subgroups

Following [1] we say that subgroups H and T of
 a group G are c-permutable in G if there exists an element x ∈ G 
 such that HTˣ = TˣH. We prove that a finite soluble group G is
 supersoluble if and only if every maximal subgroup of every Sylow
 subgroup of G is c...

Description
Summary:Following [1] we say that subgroups H and T of
 a group G are c-permutable in G if there exists an element x ∈ G 
 such that HTˣ = TˣH. We prove that a finite soluble group G is
 supersoluble if and only if every maximal subgroup of every Sylow
 subgroup of G is c-permutable with all Hall subgroups of G.
