In knot theory, the stevedore knot is one of three prime knots with crossing number six, the others being the 6 2 knot and the 6 3 knot. 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.
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.
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.
2", meaning that this is the second of three 6-crossing 3-component links to be listed. [6] [7] The Conway notation for the Borromean rings, ".1", is an abbreviated description of the standard link diagram for this link. [8]

2. Denotes the additive inverse and is read as minus, the negative of, or the opposite of; for example, –2. 3. Also used in place of \ for denoting the set-theoretic complement; see \ in § Set theory. × (multiplication sign) 1. In elementary arithmetic, denotes multiplication, and is read as times; for example, 3 × 2. 2.
The (−2, 3, 7) pretzel knot has 7 exceptional slopes, Dehn surgery slopes which give non-hyperbolic 3-manifolds. Among the enumerated knots, the only other hyperbolic knot with 7 or more is the figure-eight knot, which has 10. All other hyperbolic knots are conjectured to have at most 6 exceptional slopes. A pretzel (−2,3,7) pretzel knot.
