Legendrian torus knots were classified by Etnyre and Honda. In particular, for any smooth torus knot we know the mountain range that lists all of its Legendrian representatives. I will discuss the classification of Legendrian torus links. In this classification, a natural realization question arises: what n-tuples of points on the mountain range of a (p,q)-torus knot can occur in a Legendrian (np, nq)-torus link? Another part of the classification is to understand how many different ways an n-tuple on the mountain range can be realized as an ordered link. In particular, for Legendrian representatives of an (np,nq)-torus link is it possible to do invariant preserving permutations of the components? This is joint work with Jennifer Dalton and John Etnyre.
