New constructions of Deza digraphs

Deza digraphs were introduced in 2003 by Zhang and Wang (see [1]) as a directed graph version of Deza graphs, that also generalize the notion of directed strongly regular graphs. In this talk we give new constructions of Deza digraphs. Further, we present examples of twin and Siamese twin (directed) Deza graphs.Finally, we present a variation of directed Deza graphs, called directed Deza graph of type II, and provide a construction from finite fields.
