A worthy family of semisymmetric graphs. (English) Zbl 1021.05048
Summary: We construct semisymmetric graphs in which no two vertices have exactly the same neighbors. We show how to do this by first considering bi-transitive graphs, and then we show how to choose two such graphs so that their product is regular. We display a family of bi-transitive graphs $$D_{N}(a,b)$$ which can be used for this purpose and we show that their products are semisymmetric by applying vectors due to A. V. Ivanov [Ann. Discrete Math. 34, 273-286 (1987; Zbl 0629.05040)].
