%0 Journal Article %T The Separated Box Product of Two Digraphs %A Primo£¿ Poto£¿nik %A Stephen Wilson %J Mathematics %D 2015 %I arXiv %X A new product construction of graphs and digraphs, based on the standard box product of graphs and called the separated box product, is presented, and several of its properties are discussed. Questions about the symmetries of the product and their relations to symmetries of the factor graphs are considered. An application of this construction to the case of tetravalent edge-transitive graphs is discussed in detail. %U http://arxiv.org/abs/1511.00623v1
