Automorphisms of graph-universal Coxeter groups
by Bernhard Mühlherr.
Abstract:
A Coxeter matrix $M = (m_{ij})$ is called graph-universal if
$m_{ij} \in \{ 2,\infty \}$ for all $i \neq j$. We give a
presentation of the group of automorphisms of for any Coxeter
group associated to a graph-universal diagram.
