Novemvigintiducentillion

A novemvigintiducentillion is equal to \(10^{690}\) in the short scale and \(10^{1374}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 229th -illion number.
In the long scale, \(10^{690}\) is called quindecicentillion.
