Sestrigintaoctingentillion

A sestrigintaoctingentillion is equal to \(10^{2511}\) in the short scale and \(10^{5016}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 836th -illion number.
In the long scale, \(10^{2511}\) is called octodeciquadringentilliard.
