Octogintatrecentillion

An octogintatrecentillion is equal to \(10^{1143}\) in the short scale and \(10^{2280}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 380th -illion number.
In the long scale, \(10^{1143}\) is called nonagintacentilliard.
