Unquinquagintacentillion

An unquinquagintacentillion is equal to \(10^{456}\) in the short scale and \(10^{906}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 151st -illion number.
In the long scale, \(10^{456}\) is called seseptuagintillion.
