Sesvigintioctingentillion

A sesvigintioctingentillion is equal to \(10^{2481}\) in the short scale and \(10^{4956}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 826th -illion number.
In the long scale, \(10^{2481}\) is called tredeciquadringentilliard.
