Unsexagintacentillion

An unsexagintacentillion is equal to \(10^{486}\) in the short scale and \(10^{966}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 161st -illion number.
In the long scale, \(10^{486}\) is called unoctogintillion.
