Sesexagintaducentillion

A sesexagintaducentillion is equal to \(10^{801}\) in the short scale and \(10^{1596}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 266th -illion number.
In the long scale, \(10^{801}\) is called trestrigintacentilliard.
