Bounds in groups with trivial Frattini subgroup

Abstract

AbstractLet G be an arbitrary group with finite commutator subgroup G′. We prove that if the Frattini subgroup Φ(G) is trivial then |G:Z(G)|⩽|G′|2, and this estimate is sharp. A special case of this result was conjectured by M. Herzog, G. Kaplan and A. Lev
