Duooctogintacentillion

A duooctogintacentillion is equal to \(10^{549}\) in the short scale and \(10^{1092}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 182nd -illion number.
In the long scale, \(10^{549}\) is called unnonagintilliard.
