# How to compute n factorial algorithm

## Program for factorial of a number

Some information about these numbers can be found here and here. Visit chat. A deterministic factorial primality test. Each permutation is an operation and there are n! This is in python 3.

## The factorial function

It is O M n log n log log n , where M n log n is the time for multiplying two numbers of size n log n. Multiply the two intermediate results. The algorithm PrimeSwing , because it is the asymptotical fastest algorithm known to compute n!. Download a pdf-poster with 120 permutation trees!

A very short description of 21 algorithms for computing the factorial function n!. List all permutations of an array is O n! Traveling Salesman has a naive solution that's O n!
