Septendeciducentillion

A septendeciducentillion is equal to \(10^{654}\) in the short scale and \(10^{1302}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 217th -illion number.
In the long scale, \(10^{654}\) is called novencentillion.
