Nongentillion

A nongentillion is equal to \(10^{2703}\) in the short scale and \(10^{5400}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus and Jonathan Bower's systemIllion Numbers by Jonathan Bowers as it is the 900th -illion number.
In the long scale, \(10^{2703}\) is called quinquagintaquadringentilliard.
