Senonagintaoctingentillion

A senonagintaoctingentillion is equal to \(10^{2691}\) in the short scale and \(10^{5376}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 896th -illion number.
In the long scale, \(10^{2691}\) is called octoquadragintaquadringentilliard.
