Isomorphism of circulant combinatorial structures. (English) Zbl 0721.05010
A combinatorial structure (S,B) on an n-set S is said to be cyclic if the automorphism group of (S,B) contains a permutation which is an n-cycle (for graphs and digraphs, the term circulant is used). The author gives a summary of work that has been done on cyclic combinatorial structures with emphasis on cyclic triple systems.
