Duoseptuagintasescentillion

A duoseptuagintasescentillion is equal to \(10^{2019}\) in the short scale and \(10^{4032}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 672nd -illion number.
In the long scale, \(10^{2019}\) is called sestrigintatrecentilliard.
