Let $G$ be a $p$-group of order $p^n$ and $Phi$=$Phi(G)$ be the Frattini subgroup of $G$. It is shown that the nilpotency class of $Autf(G)$, the group of all automorphisms of $G$ centralizing $G/ Fr(G)$, takes the maximum value $n-2$ if and only if $G$ is of maximal class. We also determine the nilpotency class of $Autf(G)$ when $G$ is a finite abelian $p$-group.

Why do we call it game research and not play research? For the last decade of videogame studies, most of the attention has been paid to games as formal entities. At first, games seem easier to understand: they generally have clear rules and goals. They would be perfect machineries with formal mechanics if it was not for one factor: humans and their stubborn love for misbehaving. This talk provi...
