Prime knots
See also: List of 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
- (p, q)-torus knot - a special kind of knot that lies on the surface of an unknotted torus in R3
Composite
- Square knot (mathematics) - a composite knot obtained by taking the connected sum of a trefoil knot with its reflection
- Granny knot (mathematics) - a composite knot obtained by taking the connected sum of two identical trefoil knots
Links
- 02
1 link/Unlink - equivalent under ambient isotopy to finitely many disjoint circles in the plane - 22
1 link/Hopf link - the simplest nontrivial link with more than one component; it consists of two circles linked together exactly once (L2a1) - 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) - 63
2 link/Borromean rings - three topological circles which are linked and form a Brunnian link (L6a4) - L10a140 link - presumably the simplest non-Borromean Brunnian link
- Brunnian link - a nontrivial link that becomes trivial if any component is removed
- Pretzel link - a Montesinos link with integer tangles
