Octodecitrecentillion

An octodecitrecentillion is equal to \(10^{957}\) in the short scale and \(10^{1908}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 318th -illion number.
In the long scale, \(10^{957}\) is called novenquinquagintacentilliard.
