Duonongentillion

A duonongentillion is equal to \(10^{2709}\) in the short scale and \(10^{5412}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 902nd -illion number.
In the long scale, \(10^{2709}\) is called unquinquagintaquadringentilliard.
