Quinquagintacentillion

A quinquagintacentillion is equal to \(10^{453}\) in the short scale and \(10^{900}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 150th -illion number.
In the long scale, \(10^{453}\) is called quinseptuagintilliard.
It is referred to as quinquaginticentillion in Cookiefonster's extension of Jonathan Bowers system of -illions1.8. Extensions to the -illions II: Jonathan Bowers' -illions.
