Nonagintaseptingentillion

A nonagintaseptingentillion is equal to \(10^{2373}\) in the short scale and \(10^{4740}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 790th -illion number.
In the long scale, \(10^{2373}\) is called quinnonagintatrecentilliard.
