There is only one possible combination of a 13 digit number created from 13 digits.
In a combination, the order of the digits does not matter so that 123 is the same as 132 or 312 etc.
If there are 13 different digits (characters) there is
1 combination of 13 digits
13 combinations of 1 or of 12 digits
78 combinations of 2 or of 11 digits and so on
There are 213 - 1 = 8191 in all.
If the characters are not all different it is necessary to have more information.
