Abstract
The HOMFLY-PT polynomial is a link invariant which is effective in
determining chiral knot and link types with small crossing numbers. In this
chapter, we concentrate on knots. We provide a guide for computing the knot
types of configurations from 3D coordinates via the HOMFLY-PT polynomial using
publicly-available Linux freeware. We include data on the efficacy of HOMFLY-PT
for knot types through crossing number 16.
