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 K {\displaystyle K} , the stick number of K {\displaystyle K} , denoted by stick ( K ) {\displaystyle \operatorname {stick} (K)} , is the smallest number of edges of a polygonal path equivalent to K {\displaystyle K} .
