Untrigintaquadringentillion

An untrigintaquadringentillion is equal to \(10^{1296}\) in the short scale and \(10^{2586}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 431st -illion number.
In the long scale, \(10^{1296}\) is called sedeciducentillion.
