Sesquinquagintacentillion

A sesquinquagintacentillion is equal to \(10^{471}\) in the short scale and \(10^{936}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 156th -illion number.
In the long scale, \(10^{471}\) is called octoseptuagintilliard.
