Tresquadringentillion

A tresquadringentillion is equal to \(10^{1212}\) in the short scale and \(10^{2418}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 403rd -illion number.
In the long scale, \(10^{1212}\) is called duoducentillion.
