These equivalence classes are represented by connect-sums of n left-hand (p,2)-torus knots with a given colouring when n=1,2,...,p. This gives a 3-colour and a 5-colour analogue of the surgery presentation of a knot.This is the version published by Algebraic & Geometric Topology on 24 May 2006Geometric Topology57M25, 57M10, 57M27Surgery untying of coloured knotstext
