Abstract
Let G be a residually finite group and let an(G) denote the number of index n subgroups of G. It is shown that an(G)/n → 0 if and only if G has a finite index central subgroup whose finite quotients are all cyclic. As an application we show that the degree of a group of polynomial subgroup growth cannot lie strictly between 0 and 1.
