Extended Data Fig. 8: Summary of (m, n)-torus knots/links with different combinations of m and n.
From: Topological Chern vectors in three-dimensional photonic crystals
The colors of red, blue, green and yellow represent the first, second, third and fourth loops that wrap around the torus surface without crossing. The links with non-coprime m and n are highlighted with grey background. The simplest link is the (2, 2)-torus link, or the Hopf link on the torus surface.
