New 2-closed groups that are not automorphism groups of digraphs

Research output: Contribution to journal › Article › peer-review

Abstract

In this paper we extend the construction of Giudici, Morgan and Zhou to give the first known examples of nonregular, 2-closed permutation groups of rank greater than 4 that are not the automorphism group of any digraph. We also show that this construction only gives examples for four particular primes.
