Duononagintaquadringentillion

A duononagintaquadringentillion is equal to \(10^{1479}\) in the short scale and \(10^{2952}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 492nd -illion number.
In the long scale, \(10^{1479}\) is called sesquadragintaducentilliard.
