Guppybong

Guppybong is equal to 1020,000,000 = E20,000,000. The term was coined by Sbiis Saibian. It is equal to 1 followed by 20 million zeros. It is also called one hundred sextillisesexagintasescentilliquinsexagintasescentillion in the short scale. It is 20,000,001 digits long. This number belongs to the guppy regiment.
Guppybong is also known as "one hundred sexmilliamilliasescensexsexaginmilliasescenquinsexagintillion" according to Landon Curt Noll's The English name of a number.
Writing down the full decimal expansion would take 20 books of 400 pages each, with 2,500 digits on each page (except for the first, which would have 2,501).
