Vigintinongentillion

A vigintinongentillion is equal to \(10^{2763}\) in the short scale and \(10^{5520}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 920th -illion number.
In the long scale, \(10^{2763}\) is called sexagintaquadringentilliard.
