Quinsexagintaducentillion

A quinsexagintaducentillion is equal to \(10^{798}\) in the short scale and \(10^{1590}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 265th -illion number.
In the long scale, \(10^{798}\) is called trestrigintacentillion.
