Unoctogintatrecentillion

An unoctogintatrecentillion is equal to \(10^{1146}\) in the short scale and \(10^{2286}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 381st -illion number.
In the long scale, \(10^{1146}\) is called unnonagintacentillion.
