Quattuoroctogintaducentillion

A quattuoroctogintaducentillion is equal to \(10^{855}\) in the short scale and \(10^{1704}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 284th -illion number.
In the long scale, \(10^{855}\) is called duoquadragintacentilliard.
