WebA loop knot is a type of knot that has a fixed 'eye'. The eye can be formed via 'tying-in-the-bight' (TIB) or by non-TIB methods. An example is the Figure 8 eye knot (ABoK #1047) - which can be tied-in-the-bight to directly form the eye in a 1 stage tying process. However, when attempting to attach the F8 eye knot to a climbing harness or to a ... WebKnots are most commonly cataloged based on the minimum number of crossings present (the so-called link crossing number ). Thistlethwaite has used Dowker notation to enumerate the number of prime knots of up to 13 crossings, and alternating knots up to 14 crossings. In this compilation, mirror images are counted as a single knot type.
