Quattuoroctogintillion

A quattuoroctogintillion is equal to 10255 in America, or 10504 in the long scale by Conway and Guy's naming system.Conway and Guy. (1995) "The book of Numbers" Copernicus It is the smallest positive integer, whose full decimal expansion cannot be used at all as a page title in MediaWiki projects.
In the long scale which is commonly used in France and Germany, 10255 is called duoquadragintilliard.
