This paper demonstrates a polynomial time solution of the CSP in an important class of nonabelian groups, the extraspecial p-groups. ... The consequences of our results are practically relevant for ruling out several groups as platforms, since several nonabelian groups are constructed by combining smaller groups by taking direct and central ... Every extraspecial p-group has order p 1+2n and is a central product of n extraspecial groups of order p 3 . ...

INTRODUCTION The following p-groups are known as noncommutative p-groups that have cyclic $ma]\dot{o}mal$ subgroups: (1) $p=2$ , dihedral 2-group $D_{m}=\{x,y|x^{2^{m-1}}=y^{2}=1,yxy=x^{-1}$ ), $m\geq ... STRUCTURE OF $G$ Since the p-group $P$ is regular, it is known $H^{1}(G, k)\simeq H^{1}(N_{G}(P), k)$ and the group $G$ has the following structure: where $I=P\cap O^{p}(G)=P\cap O^{p}(N_{G}(P))$ . ...
