Kwak, Jin Ho; Lee, Jaeun Isomorphism classes of graph bundles. (English) Zbl 0739.05042 Can. J. Math. 42, No. 4, 747-761 (1990). Summary: Recently, M. Hofmeister [J. Graph Theory 12, No. 3, 437-444 (1988; Zbl 0649.05036)] counted all nonisomorphic double coverings of a graph by using its \(\mathbb{Z}_ 2\) cohomology groups, and J. Kwak and J. Lee did the same work for some finite-fold coverings. We give an algebraic characterization of isomorphic graph bundles, from which we get a formula to count all nonisomorphic graphbundles. Some applications to wheels are also discussed.
