On the order of semiregular automorphisms of cubic vertex-transitive graphs

Marco Barbieri, Valentina Grazian, Pablo Spiga

We prove that, if $Γ$ is a finite connected cubic vertex-transitive graph, then either there exists a semiregular automorphism of $Γ$ of order at least $6$ , or the number of vertic…

On the number of fixed edges of automorphisms of vertex-transitive graphs of small valency

Marco Barbieri, Valentina Grazian, Pablo Spiga

We prove that, if $Γ$ is a finite connected $3$ -valent vertex-transitive, or $4$ -valent vertex- and edge-transitive graph, then either $Γ$ is part of a well-understood family of gr…

On the Cayleyness of Praeger-Xu graphs

Marco Barbieri, Valentina Grazian, Pablo Spiga

We give a sufficient and necessary condition for a Praeger-Xu graph to be a Cayley graph.
