Quinquadragintaducentillion

A quinquadragintaducentillion is equal to \(10^{738}\) in the short scale and \(10^{1470}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 245th -illion number.
In the long scale, \(10^{738}\) is called tresviginticentillion.
