Noventrigintatrecentillion

A noventrigintatrecentillion is equal to \(10^{1020}\) in the short scale and \(10^{2034}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 339th -illion number.
In the long scale, \(10^{1020}\) is called septuagintacentillion.
