Quinquinquagintaquadringentillion

A quinquinquagintaquadringentillion is equal to \(10^{1368}\) in the short scale and \(10^{2730}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 455th -illion number.
In the long scale, \(10^{1368}\) is called octovigintiducentillion.
