This piece is approximately 6" in diameter and 1" thick. In this sculpture there are three radial pillars coming from the center to the torus, making a genus 3 surface like a steering wheel. On that surface are carved three linked knots, each one going around the outside of the torus twice before going down one pillar into the center and then back out another pillar to close the knot. These three knots link with each other at the center, and the whole design has the symmetry of the permutation group S_3. The sculpture has a patina that was removed along the raised edges so that they are visually emphasized by their lighter color.
