Quattuorseptuagintasescentillion

A quattuorseptuagintasescentillion is equal to \(10^{2025}\) in the short scale and \(10^{4044}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 674th -illion number.
In the long scale, \(10^{2025}\) is called septentrigintatrecentilliard.
