Vigintioctingentillion

A vigintioctingentillion is equal to \(10^{2463}\) in the short scale and \(10^{4920}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 820th -illion number.
In the long scale, \(10^{2463}\) is called deciquadringentilliard.
