File:12crossings-rose-rhodonea-limacon-symmetrical-knot.png

Decorative knot with twelve crossings, depicted with three-fold visual symmetry. The curves were generated from the polar coordinates equation r=b+sin(aθ), which is a slight generalization of the Limaçon and Rose/rhodonea curves, using parameters a=(3/5) and b=(3/2).
