How many knots do YOU know?

A mathematician has calculated out that there are exactly 177,147 ways to tie a tie. He has even made a program that generates types of tie-knots. The most popular tie-knot (and most likely the one you know) is the Windsor knot. Apparently, the number of wrong ways to tie a tie is even more!
