Duovigintiquadringentillion

A duovigintiquadringentillion is equal to \(10^{1269}\) in the short scale and \(10^{2532}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 422nd -illion number.
In the long scale, \(10^{1269}\) is called undeciducentilliard.
