Sesexagintaquadringentillion

A sesexagintaquadringentillion is equal to \(10^{1401}\) in the short scale and \(10^{2796}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 466th -illion number.
In the long scale, \(10^{1401}\) is called trestrigintaducentilliard.
