ON COMMUTATORS IN FINITE P-GROUPS OF ALMOST MAXIMAL CLASS

Abstract

Let Γ(G) denote the set of commutators of a group G, G′ = ⟨Γ(G)⟩ and c(G) (or cw(G)) the minimal number such that every element of G′ can be expressed as a product of at most c(G) commutators. Recently we proved that if G is a finite p-group of maximal cl
