Seseptuagintaducentillion

A seseptuagintaducentillion is equal to \(10^{831}\) in the short scale and \(10^{1656}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 276th -illion number.
In the long scale, \(10^{831}\) is called octotrigintacentilliard.
