Unknotting number. Trefoil knot without 3-fold symmetry being unknotted by one crossing switch. In the mathematical area of knot theory, the unknotting number of a knot is the minimum number of times the knot must be passed through itself ( crossing switch) to untie it. If a knot has unknotting number , then there exists a diagram of the knot ...
Stick number. 2,3 torus (or trefoil) knot has a stick number of six. In the mathematical theory of knots, the stick number is a knot invariant that intuitively gives the smallest number of straight "sticks" stuck end to end needed to form a knot. Specifically, given any knot , the stick number of , denoted by , is the smallest number of edges ...

Every non-trivial knot has bridge number at least two, so the knots that minimize the bridge number (other than the unknot) are the 2-bridge knots. It can be shown that every n-bridge knot can be decomposed into two trivial n-tangles and hence 2-bridge knots are rational knots. If K is the connected sum of K 1 and K 2, then the bridge number of ...
