Septemoctogintanongentillion

A septemoctogintanongentillion is equal to \(10^{2964}\) in the short scale and \(10^{5922}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 987th -illion number.
In the long scale, \(10^{2964}\) is called quattuornonagintaquadringentillion.
