Sesvigintiducentillion

A sesvigintiducentillion is equal to \(10^{681}\) in the short scale and \(10^{1356}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 226th -illion number.
In the long scale, \(10^{681}\) is called tredecicentilliard.
