Novenseptuagintasescentillion

A novenseptuagintasescentillion is equal to \(10^{2040}\) in the short scale and \(10^{4074}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 679th -illion number.
In the long scale, \(10^{2040}\) is called quadragintatrecentillion.
