Sexagintasescentillion

A sexagintasescentillion is equal to \(10^{1983}\) in the short scale and \(10^{3960}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 660th -illion number.
In the long scale, \(10^{1983}\) is called trigintatrecentilliard.
