Septemvigintinongentillion

A septemvigintinongentillion is equal to \(10^{2784}\) in the short scale and \(10^{5562}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 927th -illion number.
In the long scale, \(10^{2784}\) is called quattuorsexagintaquadringentillion.
