Abstract:We establish the first super-logarithmic lower bound for the number of conjugacy classes of a finite nilpotent group. In particular, we obtain that for any constant c there are only finitely many finite p-groups of order pm with at most cm conjugacy classes. This answers a question of L. Pyber.
Keywords:p-Groups   The number of conjugacy classes
