By your example, aa = 0, so ab = 1? ac = 2 then... so that makes sense...
but where does it end? az? Or is it more like hex, where it goes to af? :)
Does the progression go like:
aa = 0 to az = 25,
ba = 26... bz = 51,
ca... etc
all the way to zz, which would be a total possible number of combinations of
26^2?
The math is wrong on the example too... 160 * -4 = -640, not -480... or am I
missing something there?
