Senonagintaducentillion

A senonagintaducentillion is equal to \(10^{891}\) in the short scale and \(10^{1776}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 296th -illion number.
In the long scale, \(10^{891}\) is called octoquadragintacentilliard.
