Novemvigintioctingentillion

A novemvigintioctingentillion is equal to \(10^{2490}\) in the short scale and \(10^{4974}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 829th -illion number.
In the long scale, \(10^{2490}\) is called quindeciquadringentillion.
