## Abstract We determine necessary and sufficient conditions for a complete multipartite graph to admit a set of 1‐factors whose union is the whole graph and, when these conditions are satisfied, we determine the minimum size of such a set.

## Abstract In this paper we present a simple method for constructing infinite families of graphs defined by a class of systems of equations over commutative rings. We show that the graphs in all such families possess some general properties including regularity and biregularity, existence of speci
