Sexoctogintasescentillion

A sexoctogintasescentillion is equal to \(10^{2061}\) in the short scale and \(10^{4116}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 686th -illion number.
In the long scale, \(10^{2061}\) is called tresquadragintatrecentilliard.
