Commuting Involution Graphs for Certain Exceptional Groups of Lie Type
AbstractSuppose that G is a finite group and X is a G-conjugacy classes of involutions. The commuting involution graph $${\mathcal {C}}(G,X)$$ is the graph whose vertex set is X with $$x, y \in X$$ being joined if $$x \ne y$$ and $$xy = yx$$. Here for various exceptional Lie type groups of characteristic two we investigate their commuting involution graphs.
