The non-commuting, non-generating graph of a nilpotent group

Peter J. Cameron, Saul D. Freedman, Colva M. Roney-Dougal

For a nilpotent group $G$ , let $Ξ (G)$ be the difference between the complement of the generating graph of $G$ and the commuting graph of $G$ , with vertices corresponding to central…

On $p$ -groups with automorphism groups related to the exceptional Chevalley groups

Saul D. Freedman

Let $G^$ be the finite simply connected version of an exceptional Chevalley group, and let $V$ be a nontrivial irreducible module, of minimal dimension, for $G^$ over its f…
