Knots

Prime knots

• 0₁ knot/Unknot - a simple un-knotted closed loop
• 3₁ knot/Trefoil 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, 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"
• 10₁₆₁/Perko pair
