Sestrigintacentillion

A sestrigintacentillion is equal to \(10^{411}\) in the short scale and \(10^{816}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 136th -illion number.
In the long scale, \(10^{411}\) is called octosexagintilliard.
