A new trefoil knot

Here is a new trefoil knot by Chern. Unlike the previous trefoil knot, this new construction has much less strain and distortion. In this sense, the corresponding fullerene structure should be more stable.

(I gave this model to Prof. Qian-Er Zhang 張乾二 in Xian last August. Feb. 4, 2013)
