Septenquadringentillion

A septenquadringentillion is equal to \(10^{1224}\) in the short scale and \(10^{2442}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 407th -illion number.
In the long scale, \(10^{1224}\) is called quattuorducentillion.
