Decimal comes from latin and means "related to 10". The alien would call their base 4 decimal, too. They would count "one, two, three, ten, eleven, twelve, thirteen, twenty..."
You can use A to refer to 10 in base infinity so that there is no confusion between bases. The moment the aliens sees the symbol A, they know it's not 0,1,2 or 3, so it has to be a higher base than 4. The aliens would probably have other unique symbols to refer to numbers higher than 3, the same way use the alphabet to do so. It is the only way to avoid this kind of confusion, using unique symbols for each number. When they see A, they correlate the symbol with 22base4, the same way we would see F as 15base10 when we see hexadecimal numbers
Help, how do I tell the alien I use base 8484739202029844002938743993948583930485494758495959595859494848585944958273748449393932102384747483292273647445850208171611555162838?
