Quinseptuagintaoctingentillion

A quinseptuagintaoctingentillion is equal to \(10^{2628}\) in the short scale and \(10^{5250}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 875th -illion number.
In the long scale, \(10^{2628}\) is called octotrigintaquadringentillion.
