Generalizing it, you can only make n! combinations out of n different digits.
n! = 1 * 2 * 3 * ... * n . (Math definition: the factorial of a positive integer n, denoted by n!, is the product of all positive integers less than or equal to n)
When n = 4 , n! = 1 * 2 * 3 * 4 = 24.
If 16 digits are available, let's say 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F you can make
1 * 2 * 3 * 4 * ... * 16 = 2 ^15 * 3 ^6 * 5 ^3 * 7 ^2 * 11 * 13 = Excuse me, but I am not going to bring the product. Use your calculator (and be prepared for an overflow).
Anyway, it is:
16! = 32768 * 729 * 125 * 49 * 11 * 13 = 32768 * 729 *125 * 7007 = 32768 * 729 * 875875 = whatever... almost 20 trillion combinations of 16 different digits.
