Sesexagintaoctingentillion

A sesexagintaoctingentillion is equal to \(10^{2601}\) in the short scale and \(10^{5196}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 866th -illion number.
In the long scale, \(10^{2601}\) is called trestrigintaquadringentilliard.
