Quattuornonagintanongentillion

A quattuornonagintanongentillion is equal to \(10^{2985}\) in the short scale and \(10^{5964}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 994th -illion number.
In the long scale, \(10^{2985}\) is called septenonagintaquadringentilliard.
