A fibbish number is at least a 3 digit natural number
with the following property:
A digit is greater than or equal to the sum of previous 2 digits.
The digit 0 is not allowed.
Conjecture: There are no Fibbish Base 10 numerals exceeding 6 digits. Sounds like a phone call to Hexadecimal Number Abode.
