ABSTRACT CONSTRUCTING GRADED SEMI-TRANSITIVE ORIENTATIONS Casey Attebery A digraph is called graded if there is a labeling of its vertices into Zk, where k ! 3, so that every dart of the digraph has a label of the form (i,i + 1). We construct graded orientations of valency 4 using voltage covering techniques, where the base graph is a directed k-cy...
