The stevedore knot is listed as the 6 1 knot in the Alexander–Briggs notation, and it can also be described as a twist knot with four half twists, or as the (5,−1,−1) pretzel knot. The mathematical stevedore knot is named after the common stevedore knot , which is often used as a stopper at the end of a rope .

Like the figure-eight knot, the 6 3 knot is fully amphichiral.This means that the 6 3 knot is amphichiral, [2] meaning that it is indistinguishable from its own mirror image. In addition, it is also invertible, meaning that orienting the curve in either direction yields the same oriented knot.
2,3 torus (or trefoil) knot has a stick number of six.. In the mathematical theory of knots, the stick number is a knot invariant that intuitively gives the smallest number of straight "sticks" stuck end to end needed to form a knot.
In knot theory, the 6 2 knot is one of three prime knots with crossing number six, the others being the stevedore knot and the 6 3 knot. This knot is sometimes referred to as the Miller Institute knot , [ 1 ] because it appears in the logo [ 2 ] of the Miller Institute for Basic Research in Science at the University of California, Berkeley .
A polygonal knot is a knot whose image in R 3 is the union of a finite set of line segments. [6] A tame knot is any knot equivalent to a polygonal knot. [6] [Note 2] Knots which are not tame are called wild, [7] and can have pathological behavior. [7] In knot theory and 3-manifold theory, often the adjective "tame" is omitted. Smooth knots, for ...
11-Ketotestosterone (11-KT) is an oxidized form of testosterone that contains a keto group at the C11 position. It is related to adrenosterone, an androgen found in trace quantities in humans.
