General properties of c-circulant digraphs. (English) Zbl 0648.05024
Authors’ summary: “A digraph is said to be c-circulant if its adjacency matrix is c-circulant. This paper deals with general properties of this family of digraphs, as isomorphisms, regularity, strong connectivity, diameter and the relation between c-circulant digraphs and the line digraph technique.”
