Novenseptuagintaoctingentillion

A novenseptuagintaoctingentillion is equal to \(10^{2640}\) in the short scale and \(10^{5274}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 879th -illion number.
In the long scale, \(10^{2640}\) is called quadragintaquadringentillion.
