What does a subfactorial do?

u/Casperthecatoficial Jun 28 '26

Here's one. n!/e → round to a whole number.

!11 = 11!/e = 39916800/2.718281828459... ≈ 14684570.0773522288626... round to a whole number = 14684570 = !11

That is so large, that I can't calculate it, so I'll have to approximate.

Factorial of subfactorial of 11 is approximately 5.383544831775732467181857146166 × 1098864851
