Edge-transitive core-free Nest graphs

István Kovács

A finite simple graph is called a Nest graph if it is regular of valency and admits an automorphism with two orbits of the same length such that at least one of the sub…

Intersection density of transitive groups with cyclic point stabilizers

Ademir Hujdurović, István Kovács, Klavdija Kutnar +1

For a permutation group acting on a set , a subset of is said to be an intersecting set if for every pair of elements there exists $v…

CI-property of and for digraphs

István Kovács, Mikhail Muzychuk, Péter P. Pálfy +2

We prove that the direct product of two coprime order elementary abelian groups of rank two, as well as the direct product of a cyclic group of prime order and a cyclic group of sq…

On certain edge-transitive bicirculants of twice odd order

István Kovács, János Ruff

A graph admitting an automorphism with two orbits of the same length is called a bicirculant. Recently, Jajcay et al. initiated the investigation of the edge-transitive bicirculant…
