Sesquingentillion

A sesquingentillion is equal to \(10^{1521}\) in the short scale and \(10^{3036}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 506th -illion number.
In the long scale, \(10^{1521}\) is called tresquinquagintaducentilliard.
