Query: Construction of Directed Strongly Regular Graphs as Generalized Cayley
  Graphs   Directed strongly regular graphs were introduced by Duval in 1998 as one of
the possible generalization of classical strongly regular graphs to the
directed case. Duval also provided several construction methods for directed
strongly regular graphs. In this paper, an infinite family of directed strongly
regular graphs is constructed, as generalized Cayley graphs of cyclic groups.
