Theorem A yields the condition under which the number of solutions of equation x p k = 1 in a finite p -group is divisible by p n + k (here n is a fixed positive integer). Theorem B which is due to Avinoam Mann generalizes the counting part of the Sylow Theorem. We show in Theorems C and D that congruences for the number of cyclic subgroups of order p k which are true for abelian groups hold for more general finite groups (for example for groups with abelian Sylow p -subgroups).
