You cannot make 24 using only the digits 3, 1, 8, and 8.

24 of them.
I take it that you want to make three digits numbers with 8,7,3, and 6 without repetition. The first digit cane be selected from among 4 digits, the second from 3 digits, the third digit from 2, hence the number of three digit numbers that can be formed without repetition is 4 x 3 x 2 = 24

Assuming each of the given digits can be used only once, the answer is 24. If not, the answer is infinity.

24 different numbers.

If you want 4-digit numbers, there are 24 of them.
Using the combination C(4,3) I got the answer 24. Its either a combination or a permutation.
