Re:Markov Chains vs. Simulation: Flipping a Million Little C... by mturmon on Tuesday November 11, 2014 @12:19AM (#8588447)
Totally true.

It's a useful heuristic approximation that

  n! ~ (n/e)^n
That is, multiplying the "n" factors from 1...n is close to multiplying (n/e) upon itself "n" times.

The actual Stirling approximation is just a sqrt(2 pi n) bigger than the above, and usually it's fine to throw that away (as above).
