A septenquinquagintaquadringentillion is equal to \(10^{1374}\) in the short scale and \(10^{2742}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 457th -illion number.
In the long scale, \(10^{1374}\) is called novemvigintiducentillion.
