Vigintiquingentillion

A vigintiquingentillion is equal to \(10^{1563}\) in the short scale and \(10^{3120}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 520th -illion number.
In the long scale, \(10^{1563}\) is called sexagintaducentilliard.
