Query: Directed Strongly Regular Cayley Graphs on Dihedral groups   In this paper,we construct some directed strongly regular Cayley graphs on
dihedral groups,these generalizes some earlier constructions.We also
characterize some certain directed strongly regular Cayley graphs on dihedral
groups $D_{p^\alpha}$,where $p$ is a prime and $\alpha\geqslant 1$ is a
positive integer.
