A septenquinquagintatrecentillion is equal to \(10^{1074}\) in the short scale and \(10^{2142}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 357th -illion number.
In the long scale, \(10^{1074}\) is called novenseptuagintacentillion.
