Quintrecentillion

A quintrecentillion is equal to \(10^{918}\) in the short scale and \(10^{1830}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 305th -illion number.
In the long scale, \(10^{918}\) is called tresquinquagintacentillion.
