## Knots

### Prime knots

• 0₁ knot/Unknot - a simple un-knotted closed loop
• 3₁ knot/Trefoil knot - (2,3)-torus knot, the two loose ends of a common overhand knot joined together
• 4₁ knot/Figure-eight knot (mathematics) - a prime knot with a crossing number four
• 5₁ knot/Cinquefoil knot, (5,2)-torus knot, Solomon's seal knot, pentafoil knot - a prime knot with crossing number five which can be arranged as a pentagram
• 5₂ knot/Three-twist knot - the twist knot with three-half twists
• 6₁ knot/Stevedore knot (mathematics) - a prime knot with crossing number six, it can also be described as a twist knot with four twists
• 6₂ knot - a prime knot with crossing number six
• 6₃ knot - a prime knot with crossing number six
• 7₁ knot, septafoil knot, (7,2)-torus knot - a prime knot with crossing number seven, which can be arranged as a {7,2} star polygon
• 7₄ knot, "endless knot"
• 818 knot, "carrick mat"
• 10₁₆₁/Perko pair
• 12n242/(−2,3,7) pretzel knot
• (pq)-torus knot - a special kind of knot that lies on the surface of an unknotted torus in R3

### Composite

• 02
1
link/Unlink - equivalent under ambient isotopy to finitely many disjoint circles in the plane
• 22
1
• 42
1
link/Solomon's knot (a two component "link" rather than a one component "knot") - a traditional decorative motif used since ancient times (L4a1)
• 52
1
link/Whitehead link - two projections of the unknot: one circular loop and one figure eight-shaped loop intertwined such that they are inseparable and neither loses its form (L5a1)
