Treseptuagintaoctingentillion

A treseptuagintaoctingentillion is equal to \(10^{2622}\) in the short scale and \(10^{5238}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 873rd -illion number.
In the long scale, \(10^{2622}\) is called septentrigintaquadringentillion.
