Abstract
A Rubik’s Snake is a toy that has been around for 40 years. It can be twisted to many
interesting shapes. In particular a Rubik’s snake can be twisted to form a knot. In this paper
we study how many blocks are needed to form a composite knot with up to 8 crossings.
Also, we improved a couple of previous results for Rubik’s snake prime knots.
