The discovery of all possible ways to tie a tie depends on a mathematical formulation of the act of tying a tie. In their papers (which are technical) and book (which is for a lay audience, apart from an appendix), the authors show that necktie knots are equivalent to persistent random walks on a triangular lattice, with some constraints on how the walks begin and end.

A tenkara rod is chosen based on the environment it will be used; [8] whereas tenkara rods are typically longer than most other fishing rods, a tenkara rod's length has the distinct advantage of reaching across currents. Tenkara line: As in fly-fishing, it is the tenkara line that propels the weightless fly forward. In tenkara, the traditional ...
They were also encouraged to teach someone how to tie a knot. Even teaching someone to tie their shoelaces was sufficient. When the knots were tied, participants were encouraged to post a photo of their knot on their favorite social media site with the hashtag #WorldKnotTyingDay. [11] In 2020, the IGKT shifted the day of the celebration to ...
7 1 knot, septafoil knot, (7,2)-torus knot - a prime knot with crossing number seven, which can be arranged as a {7/2} star polygon ; 7 4 knot, "endless knot" 8 18 knot, "carrick mat" 10 161 /10 162, known as the Perko pair; this was a single knot listed twice in Dale Rolfsen's knot table; the duplication was discovered by Kenneth Perko
Figure-eight knot of practical knot-tying, with ends joined. In knot theory, a figure-eight knot (also called Listing's knot [1]) is the unique knot with a crossing number of four. This makes it the knot with the third-smallest possible crossing number, after the unknot and the trefoil knot. The figure-eight knot is a prime knot.
A two lead, three bight Turk's head is also a trefoil knot if the ends are joined together. (2,n) alternating torus knots are (2,n) Turk's head knots. [3] ((p,q) = q times around a circle in the interior of the torus, and p times around its axis of rotational symmetry.) Turk's head knots are easy to edit though hard to tie.
Knots of diverse colors were used as belts, identity tags, and as a decorative element on instruments. In the ruling palaces, knots were used to signify dignity and prestige. For religious purposes knots decorated Buddhist ornaments. The most common use of knots was in Norigae, traditional Korean ornaments worn by women to decorate clothing.
