Septenquadragintaquadringentillion

A septenquadragintaquadringentillion is equal to \(10^{1344}\) in the short scale and \(10^{2682}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 447th -illion number.
In the long scale, \(10^{1344}\) is called quattuorvigintiducentillion.
