Novemviginticentillion

A novemviginticentillion is equal to \(10^{390}\) in the short scale and \(10^{774}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 129th -illion number.
In the long scale, \(10^{390}\) is called quinsexagintillion.
