Quattuorquinquagintacentillion

A quattuorquinquagintacentillion is equal to \(10^{465}\) in the short scale and \(10^{924}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 154th -illion number.
In the long scale, \(10^{465}\) is called septenseptuagintilliard.
