Septensexagintacentillion

A septensexagintacentillion is equal to \(10^{504}\) in the short scale and \(10^{1002}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 167th -illion number.
In the long scale, \(10^{504}\) is called quattuoroctogintillion.
