Treseptuagintaducentillion

A treseptuagintaducentillion is equal to \(10^{822}\) in the short scale and \(10^{1638}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 273rd -illion number.
In the long scale, \(10^{822}\) is called septentrigintacentillion.
