trisoctahedron การใช้

• The " tetragonal trisoctahedron " is another name for the deltoidal icositetrahedron, a different polyhedron with three quadrilateral faces for every face of an octahedron.
• Sperrylite is cubic ( 2 / m3 ) and is typically seen in well-developed cubes or cuboctahedra, some of which are so highly modified that crystal edges and comers appear rounded . ( Nicol and Goldschmidt 1903 ) identified seventeen crystal forms exhibited by sperrylite, including four different trapezohedra, a trisoctahedron, five pyritohedra, and four diploids.
