Septenonagintaquadringentillion

A septenonagintaquadringentillion is equal to \(10^{1494}\) in the short scale and \(10^{2982}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 497th -illion number.
In the long scale, \(10^{1494}\) is called novenquadragintaducentillion.
