Nonagintaquadringentillion

A nonagintaquadringentillion is equal to \(10^{1473}\) in the short scale and \(10^{2940}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 490th -illion number.
In the long scale, \(10^{1473}\) is called quinquadragintaducentilliard.
