I am a little stumped at what this page says. Here's the website.


In the formula n!=5*(5-1)!=5*24=120

Where is the 24 coming from? And with strillings apx. as listed on this page
is the "e" -n Euler's conststant ? Maybe I'm getting this confused with a
factoring. Is factoring and factorials the same thing?
