Duosexagintatrecentillion

A duosexagintatrecentillion is equal to \(10^{1089}\) in the short scale and \(10^{2172}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 362nd -illion number.
In the long scale, \(10^{1089}\) is called unoctogintacentilliard.
