What’s in a Shoelace - almost 2 TRILLION possibilities to do that

What’s in a Shoelace - It’s lot more than we think.
I had this problem with my Adidas shoe only, Slipping Shoelace Knots problem. Since I travel on foot for long distances I thought I have this problem. Now I think it’s the wrong way of tying lace. I was shocked to discover that there are 2 Trillion Possibilities. Ian Fieggen’s site suggests some good combination of lace tying.

Do you know that a shoe lace can be tied - That's almost 2 TRILLION possibilities. I was amazed to read this on.

It hardly seems possible that there could be quite that many ways to feed a lace through 12 eyelets! So let's look at the mathematics:
* Feed through one of 12 eyelets from either inside or outside. That's 24 ways to start.
* Continue through one of 11 remaining eyelets from either inside or outside (x 22 more ways).
Then 10 remaining eyelets (x 20 more ways). We've only gone through three eyelets and we're already up to 24 x 22 x 20 = 10,560 ways!
* By the time we reach the last eyelet (x 2 more ways), the possible ways have multiplied to 24 x 22 x 20 x 18 x 16 x 14 x 12 x 10 x 8 x 6 x 4 x 2 ways, a staggering total of almost 2 TRILLION possibilities!
