Examples for
Permutations
The permutation is an important operation in combinatorics and in other areas of mathematics. To permute a list is to rearrange its elements. To count the permutations of a list is to count the number of unique rearrangements of the list. Wolfram|Alpha is useful for counting, generating and doing algebra with permutations.
