I was thinking last night about how hexadecimal can store more info than decimal in the same number of chars. A six-digit number in hex can have up to 16,777,216 possible values.

I don't normally see other bases used, but there is another scheme which comes up from time to time, the kind of "alphabetical" system. I guess it's technically base 26.

If use use it, a six-digit number can have up to 308,915,776 possible values.

Is it used for anything? Perl can "count" using this scheme can't it? I mean I can do "for(AA..ZZ){$x++};print $x;" and get 676 for instance.

Does it have a name?
