Let the stick number of a Knot be the least number of straight sticks needed to make a Knot .
The smallest stick number of any Knot is , where is the Trefoil Knot. If and are
Knots, then

For a nontrivial Knot , let be the Crossing Number (i.e., the least number of crossings in any projection of ). Then

The following table gives the stick number for some common knots.
