Enter your permutation in the format n r. For example, if you wanted to find 6 choose 4, you would enter 6 4. NOTICE: No negative numbers, and only integers. Numbers above 171 result in NaN or infinity, because 171! is over Scratch's number limit.
Basically the exact same as my x choose y calculator except this find permutations instead :P All me, including the permutation formula. It is n!/(n-r)! in case you want to know. IMPORTANT: This finds PERMUTATIONS, not COMBINATIONS. With this, I found that there are 59280 possible "combinations" in a combination lock. Wow!
