Twist knot

In knot theory, a branch of mathematics, a twist knot is a knot obtained by repeatedly twisting a closed loop and then linking the ends together. (That is, a twist knot is any Whitehead double of an unknot.) The twist knots are an infinite family of knots, and are considered the simplest type of knots after the torus knots.One half-twist (trefoil knot, 31)Two half-twists (figure-eight knot, 41)Three half-twists (52 knot)Four half-twists (stevedore knot, 61)Five half-twists (72 knot)Six half-twists (81 knot) In knot theory, a branch of mathematics, a twist knot is a knot obtained by repeatedly twisting a closed loop and then linking the ends together.
