Octogintaducentillion

An octogintaducentillion is equal to \(10^{843}\) in the short scale and \(10^{1680}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 280th -illion number.
In the long scale, \(10^{843}\) is called quadragintacentilliard.
