Self $2$-distance graphs
All finite simple self $2$-distance graphs with no square, diamond, or triangles with a common vertex as subgraph are determined. Utilizing these results, it is shown that there is no cubic self $2$-distance graph.

Keywords:distance graph, regular graph, forbidden subgraph

Suborbit Structure of Permutation $p$-Groups and an Application to Cayley Digraph Isomorphism
Let $P$ be a transitive permutation group of order $p^m$, $p$ an odd prime, containing a regular cyclic subgroup. The main result of this paper is a determination of the suborbits of $P$. The main result is used to give a simple proof of a recent result by J.~Morris on Cayley digraph isomorphisms.
