If the four numbers are the only numbers in the combination and the order is the only issue, there are 16 possibilities.

If you do the same problem with the combinations 1,2,3,4, how many possibilities are there? One can appear in four places, two can also, so can three and four. You have four numbers that can appear in four orders. How would I have arrived at 16?
