On the classification of 3--bridge links

Using a new way to represent links, that we call a butterfly representation, we assign to each 3-bridge link diagram a sequence of six integers, collected as a triple (p/n,q/m,s/l), such that p≥ q≥ s≥2, 0 and lt;n≤ p, 0 and lt;m≤ q and 0 and lt;l≤ s. For each 3-bridge link there exists an infinite n...
