Duosexagintaquadringentillion

A duosexagintaquadringentillion is equal to \(10^{1389}\) in the short scale and \(10^{2772}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 462nd -illion number.
In the long scale, \(10^{1389}\) is called untrigintaducentilliard.
