Sato, Iwao Graph covering and its generalization. (English) Zbl 0947.05026 Yokohama Math. J. 47, Spec. Iss., 67-88 (1999). Summary: We present some topics on graph covering and its generalization. We survey some results on enumeration of isomorphism classes of coverings of a graph and \(g\)-cyclic \(A\)-covers of a symmetric digraph, where \(A\) is a finite group and \(g\in A\). We also mention some related questions.
