Summary: For a finite group $G$ let $\Gamma ( G)$ be the (simple) graph defined on the elements of $G$ with an edge between two (distinct) vertices if and only if they generate $G$. The chromatic number of $\Gamma ( G)$ is considered for various non-solvable groups $G$.
Keywords: keywords Kneser graph, chromatic number, finite simple group, special linear group, symmetric group
