you are problbly right, however, nubmers are infinite and so we don't know if no other nubers are like that. Likley, there aren't, but we can't prove it.

Come on Mogmatt, you can prove it by inspection, don't worry about infinity, those large numbers have long names. Obviously the number is less than "one hundred"=10 letters!
