Novemoctogintaducentillion

A novemoctogintaducentillion is equal to \(10^{870}\) in the short scale and \(10^{1734}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 289th -illion number.
In the long scale, \(10^{870}\) is called quinquadragintacentillion.
