Abstract
A Rubik’s Snake is a toy that was invented over 40 years ago together with the more famous Rubik’s Cube. It can be twisted to many interesting shapes including complicated knots. Previously we have studied the shortest paths for Rubik’s Snake prime knots with up to 6 crossings and composite knots with up to 9 crossings. Here we provide some improved results for some of the knots.
Keywords: rubik’s snake, prime knot, composite knot, shortest path
