Septenquadragintacentillion

A septenquadragintacentillion is equal to \(10^{444}\) in the short scale and \(10^{882}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 147th -illion number.
In the long scale, \(10^{444}\) is called quattuorseptuagintillion.
