Webeach pair of vertices. More precisely, if s and t are vertices connected by 0, 1, 2, or 3 edges, then the presentation contains the relation st = ts, sts = tst, stst = tsts or ststst = tststs respectively. And finally, in the case of à 1, the edge labeled ∞ indicates that there is no relation cor-responding to this pair of vertices.
