There are millions of possible combinations.
I would have to say 10,000 possible combinations. (0000, 0001, 0002 through 9998, 9999)
If order doesn't matter, 15 combinations and if order does matter, 360 combinations are possible.
To calculate the number of possible combinations of the digits 1, 3, 7, and 9, we can use the formula for permutations of a set of objects, which is n! / (n-r)!. In this case, there are 4 digits and we want to find all possible 4-digit combinations, so n=4 and r=4. Therefore, the number of possible combinations is 4! / (4-4)! = 4! / 0! = 4 x 3 x 2 x 1 = 24. So, there are 24 possible combinations using the digits 1, 3, 7, and 9.
2^n possible combinations
There are 2^5 = 32 different combinations of the five traits possible.
There are 167960 combinations.
Since a number can have infinitely many digits, there are infinitely many possible combinations.
