Splittable and unsplittable graphs and configurations

Combinatorics 2018-08-24 v1

Abstract

We prove that there exist infinitely many splittable and also infinitely many unsplittable cyclic (n3)(n_3) configurations. We also present a complete study of trivalent cyclic Haar graphs on at most 60 vertices with respect to splittability. Finally, we show that all cyclic flag-transitive configurations with the exception of the Fano plane and the M\"obius-Kantor configuration are splittable.
