Novemvigintisescentillion

A novemvigintisescentillion is equal to \(10^{1890}\) in the short scale and \(10^{3774}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 629th -illion number.
In the long scale, \(10^{1890}\) is called quindecitrecentillion.
