Duodecinongentillion

A duodecinongentillion is equal to \(10^{2739}\) in the short scale and \(10^{5472}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 912th -illion number.
In the long scale, \(10^{2739}\) is called sesquinquagintaquadringentilliard.
