Large number

The phrase "large number" has a subjective meaning, which is unsatisfactory for googologists because their studies rely on the definition of the term. Informally, it could be defined as "a number larger than any one used in everyday life." To a politician, this may be a trillion; to a cosmologist, 1080.

Sbiis Saibian suggested defining a large number as any greater than 1, offering the alternate term superuniary number. This is because every small number is a reciprocal of the large number and otherwise.

Googology Wiki defined 100 as the smallest large numer. In January 2013, this restriction was lifted.
