Senonagintasescentillion

A senonagintasescentillion is equal to \(10^{2091}\) in the short scale and \(10^{4176}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 696th -illion number.
In the long scale, \(10^{2091}\) is called octoquadragintatrecentilliard.
