What Is A permutation?
Permutations vs. Combinations
- Permutations are closely related to the concept of combinations. Combinations, however, are order agnostic. That is – combinations refer to how many subsets you can choose out of a whole set without caring about the order. The best way to remember is: "a combination lock is a lie". Since you can't enter the code into a lock in any order, a combination lock is actually a permutati…
Formula For Permutations
- The formula for the calculating permutations is: Where: 1. n – the size of the set 2. r – the size of the subset you are choosing Note that the factorialof 0 is 1. In the case where you are not picking a subset and only reordering the larger set, you only need to calculation n!.
Using The permutation Calculator
- To compute the total number of permutations, first enter "n", the total number of things in your set. Next, enter "r" which is how large of a subset you would like to calculate. (If you aren't taking a subset, r can be the same as n). After that, leave the "Permutations or Combinations?" pulldown menu on Permutations, unless you don't care about or...
