Quattuorseptuagintaoctingentillion

A quattuorseptuagintaoctingentillion is equal to \(10^{2625}\) in the short scale and \(10^{5244}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 874th -illion number.
In the long scale, \(10^{2625}\) is called septentrigintaquadringentilliard.
