In both combinations and permutations, we must draw elements from a set without repetition. (e.g., the same runner cannot win both 1st and 2nd place, nor the same person serve on two seats of the same committee).

However, in what we call a "combination lock," something like 35-12-35 is generally a perfectly valid series of numbers.
