Noventrigintasescentillion

A noventrigintasescentillion is equal to \(10^{1920}\) in the short scale and \(10^{3834}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 639th -illion number.
In the long scale, \(10^{1920}\) is called vigintitrecentillion.
