"Combinations" is picking subsets where order doesn't matter. For "permutations", order matters and you use the full set, not subsets. So mentioning "combinations" when computing permutations is going to confuse people.

My favorite is Permuting with duplicates and no memory. A simple search or Super Search will turn up lots of other ones.
