Octosexagintatrecentillion

An octosexagintatrecentillion is equal to \(10^{1107}\) in the short scale and \(10^{2208}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 368th -illion number.
In the long scale, \(10^{1107}\) is called quattuoroctogintacentilliard.
