  • Construction of infinite families of vertex-transitive directed strongly regular graphs
    García, Maria Asuncion ...
    We introduce an infinite family of permutation groups, which are the complete automorphism groups of two different families of directed strongly regular graphs. For both families, there is a cyclic ... subgroup of the permutation group which acts semiregularly on the set of vertices of the directed graph and has two orbits. One of the two series gives an infinite number of directed strongly regular graphs admitting a cyclic semiregular automorphism group with structure and an automorphism group for which only three sporadic examples were previously known.
