Septenseptuagintaoctingentillion

A septenseptuagintaoctingentillion is equal to \(10^{2634}\) in the short scale and \(10^{5262}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 877th -illion number.
In the long scale, \(10^{2634}\) is called noventrigintaquadringentillion.
