On pseudofrobenius imprimitive association schemes
Ilia Ponomarenko, Grigory Ryabov
An (association) scheme is said to be Frobenius if it is the scheme of a Frobenius group. A scheme which has the same tensor of intersection numbers as some Frobenius scheme is sai…
On Cayley representations of central Cayley graphs over almost simple groups
Jin Guo, Wenbin Guo, Grigory Ryabov +1
A Cayley graph over a group is said to be central if its connection set is a normal subset of . We prove that every central Cayley graph over a simple group has at most…
On WL-rank and WL-dimension of some Deza dihedrants
Grigory Ryabov, Leonid Shalaginov
The WL-rank of a graph is defined to be the rank of the coherent configuration of . The WL-dimension of is defined to be the smallest positive integer for which …
On WL-rank of Deza Cayley graphs
Dmitry Churikov, Grigory Ryabov
The WL-rank of a digraph is defined to be the rank of the coherent configuration of . We construct a new infinite family of strictly Deza Cayley graphs for which the WL-rank…
Normal Cayley digraphs of cyclic groups with CI-property
Jin-Hua Xie, Yan-Quan Feng, Grigory Ryabov +1
A Cayley (di)graph of a group with respect to a subset of is called normal if the right regular representation of is a normal subgroup in the full automo…
