Septenquadragintaducentillion

A septenquadragintaducentillion is equal to \(10^{744}\) in the short scale and \(10^{1482}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 247th -illion number.
In the long scale, \(10^{744}\) is called quattuorviginticentillion.
