Duooctogintaducentillion

A duooctogintaducentillion is equal to \(10^{849}\) in the short scale and \(10^{1692}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 282nd -illion number.
In the long scale, \(10^{849}\) is called unquadragintacentilliard.
