SH(3)-Gordian distances between knots with up to seven crossings

摘要

The SH(3)-move is an unknotting operation on oriented knots, and the SH(3)-Gordian distance of two knots is the minimum number of SH(3)-moves needed to transform one into the other, which is half of the coherent band-Gordian distance. We give a table of SH(3)-Gordian distances between knots with up to seven crossings. (C) 2015 Elsevier B.V. All rights reserved.
