Duosexagintaducentillion

A duosexagintaducentillion is equal to \(10^{789}\) in the short scale and \(10^{1572}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 262nd -illion number.
In the long scale, \(10^{789}\) is called untrigintacentilliard.
