Septenducentillion

A septenducentillion is equal to \(10^{624}\) in the short scale and \(10^{1242}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 207th -illion number.
In the long scale, \(10^{624}\) is called quattuorcentillion.
