I. Torisu, THE DETERMINATION OF THE PAIRS OF 2-BRIDGE KNOTS OR LINKS WITH GORDIAN DISTANCE ONE, Proceedings of the American Mathematical Society, 126(5), 1998, pp. 1565-1571
We thoroughly determine the pairs of two-bridge knots or links with Go
rdian distance one. In addition, we examine the Gordian distance betwe
en a Montesinos knot (or link) and a two-bridge knot (or link).
