Sexoctogintacentillion

A sexoctogintacentillion is equal to \(10^{561}\) in the short scale and \(10^{1116}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 186th -illion number.
In the long scale, \(10^{561}\) is called trenonagintilliard.
