Abstract

The family OG(4)\mathcal{OG}(4) consisting of graph-group pairs (Γ,G)(\Gamma, G), where Γ\Gamma is a finite, connected, 4-valent graph admitting a GG-vertex-, and GG-edge-transitive, but not GG-arc-transitive action, has recently been examined using a normal quotient methodology. A subfamily of OG(4)\mathcal{OG}(4) has been identified as `basic', due to the fact that all members of OG(4)\mathcal{OG}(4) are normal covers of at least one basic pair. We provide an explicit classification of those basic pairs (Γ,G)(\Gamma, G) which have at least two independent cyclic GG-normal quotients (these are GG-normal quotients which are not extendable to a common cyclic normal quotient).
