Noventrigintaducentillion

A noventrigintaducentillion is equal to \(10^{720}\) in the short scale and \(10^{1434}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 239th -illion number.
In the long scale, \(10^{720}\) is called viginticentillion.
