Quinvigintitrecentillion

A quinvigintitrecentillion is equal to \(10^{978}\) in the short scale and \(10^{1950}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 325th -illion number.
In the long scale, \(10^{978}\) is called tresexagintacentillion.
