Novenducentillion

A novenducentillion is equal to \(10^{630}\) in the short scale and \(10^{1254}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 209th -illion number.
In the long scale, \(10^{630}\) is called quincentillion.
\(10^{630}\) is also called tentaggoogol.
