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
Signature of a knot Signature of a knot The signature of a knot is a topological invariant in knot theory. It may be computed from the Seifert surface. Given a knot "K" in the 3-sphere, it has a Seifert surface "S" whose boundary is "K". The Seifert form of "S" is the pairing formula_1 given by taking the linking number formula_2 where formula_3 and formula_4 indicate the translates of "a" and "b" respectively in the positive and negative directions of the normal bundle to "S". Given a basis formula_5 for formula_6 (where "g" is the genus of the surface) the Seifert form can be
