Abstract

A finite 𝑝-group 𝐺 is said to be 𝑑-maximal if d ⁒ ( H ) < d ⁒ ( G ) for every subgroup H < G , where d ⁒ ( G ) denotes the minimal number of generators of 𝐺. A similar definition can be formulated when 𝐺 is acted on by some group 𝐴. In this paper, we extend earlier results of Kahn and Laffey to this more general setting and we answer a question of Berkovich on minimal non-metacyclic 𝑝-groups.

Acknowledgements

We would like to thank the referees for their invaluable comments and suggestions which have considerably improved the presentation of this paper. We are also grateful to Professor Bruno Kahn for several enlightening comments and for providing us with some of his early manuscripts on the subject. The first author would like to thank Professor B. Eick for her hospitality during his visit to UniversitΓ€t Braunschweig and for the invaluable things he learned from her.
