Septenquinquagintaducentillion

A septenquinquagintaducentillion is equal to \(10^{774}\) in the short scale and \(10^{1542}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 257th -illion number.
In the long scale, \(10^{774}\) is called novemviginticentillion.
