Chinese button knot method that does not require a carrick bend as a first step, and does not produce a lanyard loop that needs to be reduced when used as a button. This method provides just the button, a spherical basket weave knot, in the style of Turk's head knot or diamond knot. Instructions for tying Chinese button knot in single configuration using this method as illustrated in the adjacent image, with four steps in tying it; thin red lines showing the move(s) to get to the next step: Chinese button knot Chinese button knot is essentially a diamond knot where the lanyard
Mutation (knot theory) endpoints of the tangle. There is also a rotation that results from composition of the reflections. A mutation replaces the original tangle by a tangle given by any of these operations. The result will always be a knot and is called a mutant of "K". Mutants can be difficult to distinguish as they have a number of the same invariants. They have the same hyperbolic volume (by a result of Ruberman), and have the same HOMFLY polynomials. Mutation (knot theory) In the mathematical field of knot theory, a mutation is an operation on a knot that can produce different knots.
