Multisets are sets which allow repetitions, but the order does not matter.

If you wish to allow repetitions and the order does matter, you are looking for a sequence.

Multisets are sometimes known as "bags". –  Barry Fruitman Feb 24 '13 at 19:35
    
I never heard that terminology; but then again I haven't really worked with multisets. –  Asaf Karagila Feb 24 '13 at 19:36
