Septemvigintiquadringentillion

A septemvigintiquadringentillion is equal to \(10^{1284}\) in the short scale and \(10^{2562}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 427th -illion number.
In the long scale, \(10^{1284}\) is called quattuordeciducentillion.
