Septenseptuagintaducentillion

A septenseptuagintaducentillion is equal to \(10^{834}\) in the short scale and \(10^{1662}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 277th -illion number.
In the long scale, \(10^{834}\) is called noventrigintacentillion.
