Unvigintinongentillion

An unvigintinongentillion is equal to \(10^{2766}\) in the short scale and \(10^{5526}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 921st -illion number.
In the long scale, \(10^{2766}\) is called unsexagintaquadringentillion.
