Septemoctingentillion

A septemoctingentillion is equal to \(10^{2424}\) in the short scale and \(10^{4842}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 807th -illion number.
In the long scale, \(10^{2424}\) is called quattuorquadringentillion.
