Unquadragintaducentillion

An unquadragintaducentillion is equal to \(10^{726}\) in the short scale and \(10^{1446}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 241st -illion number.
In the long scale, \(10^{726}\) is called unviginticentillion.
