Yes, Mark, I meant, that 26*26 is the number of all possible initials. Now you can take the number of all UT members and divide by this number. It would be a possibility of UT member to be with these two initials.

For instance, I clearly didn't mean Sergey in my reply to Jess.

My initials are the same as Nick Nekloudov...
