|Sometimes what looks like an impressive knot isn't a knot at all. Magicians and escape artists are experts at tying phony knots. Though magicians like knots that can fool people, mathematicians are mostly interested in real knots, especially knots that can't be undone. A mathematician's knot is always in a piece of rope that has both ends stuck together. They now know there are exactly 1,701,936 knots with 16 or fewer crossings...
