The group $C_{p}^{4} \times C_{q}$ is a DCI-group

István Kovács, Grigory Ryabov

We prove that the group $C_{p}^{4} \times C_{q}$ is a DCI-group for distinct primes $p$ and $q$ , that is, two Cayley digraphs over $C_{p}^{4} \times C_{q}$ are isomorphic if and only if their c…

Existence of non-Cayley Haar graphs

Yan-Quan Feng, István Kovács, Jie Wang +1

A Cayley graph of a group $H$ is a finite simple graph $Γ$ such that its automorphism group $Aut (Γ)$ contains a subgroup isomorphic to $H$ acting regularly on $V (Γ)$ , while a…
