Octononagintacentillion

An octononagintacentillion is equal to \(10^{597}\) in the short scale and \(10^{1188}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 198th -illion number.
In the long scale, \(10^{597}\) is called novenonagintilliard.
