Unquadragintillion

An unquadragintillion is equal to 10126 in the short scale, or \(10^{246}\) in the long scale by Conway and Guy's naming systemConway and Guy. (1995) "The book of Numbers" CopernicusThe Conway-Wechsler SystemSteve Olsen, Big-Ass Numbers and Jonathan Bowers system.
In the long scale which is commonly used in France and Germany, \(10^{126}\) is called unvigintillion.
10126 was called kathana in language of the 1st century B.C.https://digitalcommons.butler.edu/cgi/viewcontent.cgi?article=2344&context=wordways
