Sesquadragintacentillion

A sesquadragintacentillion is equal to \(10^{441}\) in the short scale and \(10^{876}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 146th -illion number.
In the long scale, \(10^{441}\) is called treseptuagintilliard.
