Novencentillion

A novencentillion is equal to \(10^{330}\) in the short scale and \(10^{654}\) in the long scale by Conway and Guy's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 109th -illion number.
In the long scale, \(10^{330}\) is called quinquinquagintillion.
