Quinvigintioctingentillion

A quinvigintioctingentillion is equal to \(10^{2478}\) in the short scale and \(10^{4950}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 825th -illion number.
In the long scale, \(10^{2478}\) is called tredeciquadringentillion.
