Octononagintaquadringentillion

An octononagintaquadringentillion is equal to \(10^{1497}\) in the short scale and \(10^{2988}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 498th -illion number.
In the long scale, \(10^{1497}\) is called novenquadragintaducentilliard.
