Octooctingentillion

An octooctingentillion is equal to \(10^{2427}\) in the short scale and \(10^{4848}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 808th -illion number.
In the long scale, \(10^{2427}\) is called quattuorquadringentilliard.
