Quinsexagintaquadringentillion

A quinsexagintaquadringentillion is equal to \(10^{1398}\) in the short scale and \(10^{2790}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 465th -illion number.
In the long scale, \(10^{1398}\) is called trestrigintaducentillion.
