Abstract

Let G be a group and H₁,…, H_s be subgroups of G of indices d₁,…, d_s respectively. In 1974, M. Herzog and J. Schönheim conjectured that if {inline formula present}, α₁ ∈ G, is a coset partition of G, then d₁,…, d_s cannot be distinct. We consider the Herzog-Schönheim conjecture for free groups of finite rank and propose a new approach, based on an extension of the Mirsky-Newman, Davenport-Rado result for {inline formula preset}.
