I need to know the total possible unique variations there can be on an identifier that is made up of 20 alphanumeric characters, where the characters are A to Z (all upper case), and the digits 0 to 9.

0What do you mean by 'variations' and 'identifier' here? Are you looking for the number of ways that you can form a string of $20$ characters from A-Z and 0-9? – 2012-09-27

0Yes. I am referring to the 'LEI' or "legal entity identifier' that all hedge funds must start using. It consist of the letters A through Z and the numbers 0 to 9. I was wondering on how many permutations there are. It looks like I already have my answer, thanks to all! – 2012-09-27
