Septemoctogintaquadringentillion

A septemoctogintaquadringentillion is equal to \(10^{1464}\) in the short scale and \(10^{2922}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 487th -illion number.
In the long scale, \(10^{1464}\) is called quattuorquadragintaducentillion.
