Research Abstract

It is well-known that any two knot diagrams which represent the same knot are connected by a finite sequence of Reidemeister moves. We show that the minimal sequence of Reidemister moves connecting the usual diagram of the (n+1, n)-torus knot and that of the (n, n+1)-torus knot contains precisely {(n-1)n(2n-1)/6}+1 Reidemeister moves.
