Septensescentillion

A septensescentillion is equal to \(10^{1824}\) in the short scale and \(10^{3642}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 607th -illion number.
In the long scale, \(10^{1824}\) is called quattuortrecentillion.
