Abstract:
Giudici, Li and Xia (J. Combin. Theory Ser. B 127 (2017), 1-13.) constructed the first known family of vertex-primitive \(2\)-arc-transitive digraphs besides directed cycles. Digraphs in their construction are of order at least \(30758154560\). A question is that whether exists examples with smaller order. In this talk, I will introduce our work on this question. It is a join work with Yan-Quan Feng (my advisor) and Binzhou Xia.
