Summary

edit
Description Decorative knot with twelve crossings, depicted with four-fold symmetry. This is topologically equivalent to File:12crossings-fourfold-symmetric.svg and File:Circular-cross-decorative-knot-12crossings.svg (see http://katlas.math.toronto.edu/wiki/K12a975 ), but only uses orthogonal straight lines.
