ab: Let $M$ be a minimal generating set of the cyclic group $Z_n$ and let
    $\widetilde M = \{m, - m \mid m \in M\}$. Let $M \subseteq S \subseteq
    \widetilde M$. The authors prove that if a circulant digraph of order
    $n$ with symbol $T$ is isomorphic to the circulant digraph of order $n$
    with symbol $S$, then there exists an $a \in Z^*_n$ such that $T = aS$.
    They also determine the automorphism group of the circulant digraph
    with symbol $S$.
