Ummm, there wouldn't be an "aa" or "bb" M = Million(s) B = Billion(s) T = Trillion(s) Q = Quadrillion(s) Qt = Quintillion(s) Sx = Sextillion(s) <---- if that's blocked, oh well. You can figure it out Sp = Septillion(s) Ot = Octillion(s) Nn = Nonillion(s) And you keep going... so this would in fact be an easier fix.
