Duoquadragintaducentillion

A duoquadragintaducentillion is equal to \(10^{729}\) in the short scale and \(10^{1452}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 242nd -illion number.
In the long scale, \(10^{729}\) is called unviginticentilliard.
