Septensexagintanongentillion

A septensexagintanongentillion is equal to \(10^{2904}\) in the short scale and \(10^{5802}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 967th -illion number.
In the long scale, \(10^{2904}\) is called quattuoroctogintaquadringentillion.
