The IOC site for the 1896, 1900 and 1904 Summer Olympic Games does not include Mixed teams (teams of athletes from different nations) as a separate "nation" when counting participating nations. At the same time, the IOC shows Mixed teams in the results of competitions where these teams competed. Thus, specified number of national teams plus Mixed teams participated in the Games.
