Quinnonagintaducentillion

A quinnonagintaducentillion is equal to \(10^{888}\) in the short scale and \(10^{1770}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 295th -illion number.
In the long scale, \(10^{888}\) is called octoquadragintacentillion.
