Depending on the way there are counted, there are thirteen or fifteen such shapes. Of two of these shapes, there are two versions, which cannot be made congruent using rotation. The Archimedean solids are named after the Ancient Greek mathematician Archimedes, who probably discovered them in the 3rd century BC. The writings of Archimedes have been lost, but Pappus of Alexandria summarized them in the 4th century. During the Renaissance, artists and mathematicians valued "pure forms" and rediscovered all of these forms. Johannes Kepler probably completed this search around 1620.
Constructing an Archimedean solid takes at least two different polygons.
Platonic solids can be turned into Archimedean solids by following a series of rules for their construction.
The following is a listing of all Archimedean solids

Soviet Philatelic Association
Soviet Philatelic Association (SFA) was a business run by the Soviet Union authorities in the field of philately.
Two early philatelic public entities existed in the Soviet Union. These were All-Russian Society of Philatelists (created in 1922) and Philatelic International (or Filintern organised in 1924). In July 1924, an ""All-Union Philatelic Association of Socialist Soviet Republics"" was formed. It was called the "State Philatelic Organization". This association was entrusted to Feodor Chuchin. He also supervised another state body, Organisation of the Commissioner for Philately and Scripophily. The All-Union Philatelic Association ceased to exist soon after. It lacked a published decree of the All-Russian Central Executive Committee (VTsIK) and RSFSR Sovnarkom.
On 25 October 1926, a new association was established in Moscow by VTsIK and Sovnarkom decree. It replaced the Organisation of the Commissioner for Philately and Scripophily. SFA sold Soviet stamps to foreign dealers, Soviet philatelists, and schoolboys. These latter glued their stamps into school notebooks because of a lack of stamp albums.
The SFA organ was the journal "Sovetskii Filatelist" ("Soviet Philatelist").
In 1938, the Soviet Philatelic Association was replaced with the Chief Philatelic Bureau.
Hexacorallia
Hexacorallia is a large subclass of Anthozoa in the aquatic phylum Cnidaria.
It has about 4,300 species, all polyps, generally with 6-fold symmetry. It includes all the stony corals, most of which are colonial and reef-forming. It also contains the sea anemones, tube anemones, and zoanthids, in six living orders.
The Hexacorallia are distinguished from the other subclass of Anthozoa, the Octocorallia, because they have six or less axes of symmetry in their body structure and only single rows of tentacles. They are formed of individual soft polyps which in some species live in colonies and secrete a calcite skeleton. As with all Cnidarians, these organisms have a complex life cycle including a mobile planktonic phase and a later sessile phase.
Hexacorallia also include the extinct orders of the rugose corals and tabulate corals. They built the coral reefs of the Palaeozoic era. In fact, there are a total of eight extinct orders of the Hexacorallia, which shows it has always been an important group of marine organisms.
Antiprism
In geometry an antiprism is a polyhedron. It is made of two copies of a regular polygon. These polygons are connected using an alternating band of triangles. To connect an n-sided polygon, 2n triangles are needed. Antiprisms are similar to prisms, but prisms use parallelograms for the bands at the side.
A right antiprism uses a right angle to connect the base polygons to the band of triangles. A uniform antiprism uses equilateral triangles as base surfaces.
Chinx
Lionel Pickens (December 4, 1983 – May 17, 2015), better known by his stage name Chinx (formerly Chinx Drugz), was an American rapper from Queens, New York. He was a member of French Montana's Coke Boys group and record label. Other members are Cheeze, Flip, and Lil Durk. He was best known for his raps on the "Coke Boys" mixtapes and the "Cocaine Riot" mixtape series. He died from a fatal gunshot wound after a drive-by shooting in Jamaica, Queens on May 17, 2015.
On how he got started rapping, Chinx said: "I started rapping at the table in junior high school for fun with the homies and then by 9th grade is when I started taking music seriously. At that point is when I started investing my street money into my studio time and trying to find my sound."
On May 17, 2015, New York police officers (NYPD) went, after a 911 call, to Briarwood, Queens at about 4:00 a.m. There, they found Chinx and another victim in a car at Queens Boulevard and 84th Drive. Chinx was rushed to Jamaica Medical Center in Jamaica, Queens with gunshot wounds. There he was pronounced dead, at age 31.
Philatelic International
Philatelic International (Filintern) was an international philatelic society of collector-workers in the 1920s to 1940s.
The creation of the Filintern was set up at a conference in Moscow in 22 to 30 June 1924. Its formation was greeted by all branches of the All-Russian Society of Philatelists and at the same time by the Soviet Esperantists. At the conference opening, Feodor Chuchin, Commissioner for Philately and Scripophily, declared:
A program for the Filintern's central organ was developed that included:
Filintern facilitates the goals of philatelists, scripophilists and Esperantists. Within Filintern, they could:
Using philately, scripophily and Esperanto, the Soviet authorities also hoped for promoting communist propaganda among the foreign proletariat.
The Philatelic International's organ was the journal . Its Editor was a prominent Russian philatelist L. K. Eichfuss. The first issue of the journal appeared in January 1925.
Chinchorro mummies
The Chinchorro mummies are mummified remains of people from the South American Chinchorro culture, found in what is now northern Chile and southern Peru. They are the oldest examples of artificially mummified human remains. The oldest are 7,000 years old. The mummies continued to be made until about 1800 B.C.
They were first studied by the Andean archaeologist Max Uhle in 1914. Today, over 280 mummies have been found. About 120 of them are kept at the University of Tarapaca museum. Recently, scientist saw that some of the mummies are melting. This is because the increased humidity due to climate change has let microbes attack the skin.
Shell mounds and bone chemistry suggest that 90% of the diet of these people was seafood.
Uhle categorized the types of mummification he saw into three categories: simple treatment, complex treatment, and mud-coated mummies. Since then, other archaeologists refined his classification and now mostly use the following classification of Chinchorro mummification: natural, black, red, mud-coated and bandage mummies. The two most common techniques used in Chinchorro mummification were the black mummies and the red mummies.
