Question: Information: - Ernest Barberolle ( 16 October 1861 -- 5 September 1948 ) was a French rower who competed in the Olympic games in 1920 . He won a silver medal , along with Gabriel Poix and Maurice Bouton in the coxed pairs in Antwerp . - The modern Olympic Games or Olympics are leading international sporting events featuring summer and winter sports competitions in which thousands of athletes from around the world participate in a variety of competitions. The Olympic Games are considered the world's foremost sports competition with more than 200 nations participating. The Olympic Games are held every four years, with the Summer and Winter Games alternating by occurring every four years but two years apart. - The 1920 Summer Olympics, officially known as the Games of the VII Olympiad, were an international multi-sport event in 1920 in Antwerp, Belgium. In March 1912, during the 13th session of the IOC, the bid on the behalf of Belgium to host the 1920 Summer Olympics was made by Baron Edouard de Laveleye, president of the Belgian Olympic Committee and of the Royal Belgian Football Association. No fixed host city was proposed at the time. - Maurice Bouton (February 24, 1892 in Paris June 15, 1965) was a French rower who competed in the 1920 Summer Olympics and in the 1924 Summer Olympics. - The 1924 Summer Olympics, officially known as the Games of the VIII Olympiad, were an international multi-sport event which was celebrated in 1924 in Paris, France. It was the second time Paris hosted the games, after 1900. The selection process for the 1924 Summer Olympics consisted of six bids, and Paris was selected ahead of Amsterdam, Barcelona, Los Angeles, Prague, and Rome. The selection was made at the 20th IOC Session in Lausanne in 1921. - Gabriel Augustin Poix (November 8, 1888 January 23, 1946) was a French rower who competed in the 1912 Summer Olympics and in the 1920 Summer Olympics. - The 1912 Summer Olympics (Swedish: "Olympiska sommarspelen 1912"), officially known as the Games of the V Olympiad, were an international multi-sport event held in Stockholm, Sweden, between 5 May and 22 July 1912. Twenty-eight nations and 2,408 competitors, including 48 women, competed in 102 events in 14 sports. With the exception of tennis (starting on 5 May) and football and shooting (both starting on 29 June), the games were held within a month with an official opening on 6 July. It was the last Olympics to issue solid gold medals and, with Japan's debut, the first time an Asian nation participated. Stockholm was the only bid for the games, and was selected in 1909.

Answer: 1920 summer olympics

input: Please answer the following: Information: - In geometry, a translation "slides" a thing by a: "T"(p) = p + a. - In geometry , a tile substitution is a method for constructing highly ordered tilings . Most importantly , some tile substitutions generate aperiodic tilings , which are tilings whose prototiles do not admit any tiling with translational symmetry . The most famous of these are the Penrose tilings . Substitution tilings are special cases of finite subdivision rules , which do not require the tiles to be geometrically rigid . - Geometry (from the ; "geo-" "earth", "-metron" "measurement") is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the field of geometry is called a geometer. - An aperiodic tiling is a non-periodic tiling with the additional property that it does not contain arbitrarily large periodic patches. A set of tile-types (or prototiles) is aperiodic if copies of these tiles can form only non-periodic tilings. The Penrose tilings are the best-known examples of aperiodic tilings. - In the mathematical theory of tessellations, a prototile is one of the shapes of a tile in a tessellation. What entity does 'substitution tiling' has the relation 'subclass of' with?
++++++++++
output:
tessellation
