Abstract

Let GG be a Beauville finite pp-group. If GG exhibits a `good behaviour' with respect to taking powers, then every lift of a Beauville structure of G/Φ(G)G/\Phi(G) is a Beauville structure of GG. We say that GG is a Beauville pp-group of wild type if this lifting property fails to hold. Our goal in this paper is twofold: firstly, we fully determine the Beauville groups within two large families of pp-groups of maximal class, namely metabelian groups and groups with a maximal subgroup of class at most 22; secondly, as a consequence of the previous result, we obtain infinitely many Beauville pp-groups of wild type.
