Septensexagintillion

A septensexagintillion is equal to 10204 in the short scale, or 10402 in the long scale by Conway and Guy's naming system.Conway and Guy. (1995) "The book of Numbers" CopernicusRobert Munafo The Conway-Wechsler System. Retrieved 2023-02-05.Steve Olsen Big-Ass Numbers. Retrieved 2023-02-05.Fish 
In the long scale which is commonly used in France and Germany, 10204 is called quattuortrigintillion.
