Exceptional groups and the s-arc-transitivity of vertex-primitive digraphs, II
Lei Chen, Fu-Gang Yin
In this paper, we study the primitive actions of almost simple groups with socle \(E_7(q)\) or \(E_8(q)\) on an \(s\)-arc-transitive digraph. Our motivation goes back to the questi…

Exceptional groups and the -arc-transitivity of vertex-primitive digraphs, I
Fu-Gang Yin, Lei Chen
In this paper, we study the primitive actions of almost simple exceptional groups of Lie type on \(s\)-arc-transitive digraphs. Our motivation is the following question posed by Gi…
