Septemvigintioctingentillion

A septemvigintioctingentillion is equal to \(10^{2484}\) in the short scale and \(10^{4962}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 827th -illion number.
In the long scale, \(10^{2484}\) is called quattuordeciquadringentillion.
