Prime knots
A table of prime knots, knots which are (in a certain sense) indecomposable, up to seven crossings (excluding mirror images) labelled with Alexander–Briggs notation. The unknot is not considered prime. A knot in mathematics is an embedding of a circle in 3-dimensional Euclidean space. The branch of mathematics that studies knots is known as knot theory.Image credit: Jkasd
