Finite groups with permutable complete Wielandt sets of subgroups

Let 𝒲 be a set of nilpotent Hall subgroups of a finite group G . We say that 𝒲 is a Wielandt set if for each prime p dividing | G | there is exactly one subgroup W ∈ 𝒲 such that p divides | W |. In this paper, we study the influence of Wielandt sets on the structure of G . In particular, we give conditions under which a normal subgroup of a finite group is hypercyclically...
