Octononagintaducentillion

An octononagintaducentillion is equal to \(10^{897}\) in the short scale and \(10^{1788}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 298th -illion number.
In the long scale, \(10^{897}\) is called novenquadragintacentilliard.
