Nonagintasescentillion

A nonagintasescentillion is equal to \(10^{2073}\) in the short scale and \(10^{4140}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 690th -illion number.
In the long scale, \(10^{2073}\) is called quinquadragintatrecentilliard.
