Project Details

Description

A regular digraph in which the number of common out-neighbours of two vertices depend only on the adjacency between the vertices is called a normally regular digraph.The motivation for studying these digraphs came from investigation of large bipartite graphs with small diameter. Normally regular digraphs generalize non-symmetric 3-class association schemes.

We find several constructions and some non-existence results and results 

characterizing normally regular digraphs with certain parameters.
