The tetractys. The tetractys (Greek: τετρακτύς), or tetrad, [1] or the tetractys of the decad [2] is a triangular figure consisting of ten points arranged in four rows: one, two, three, and four points in each row, which is the geometrical representation of the fourth triangular number.
Bipyramids, the duals of the infinite set of prisms, with triangle faces: any multiple of 4 (so that a face will face up), starting from 8; Disphenoids, an infinite set of tetrahedra made from congruent non-regular triangles: 4 sides. This is a less symmetric tetrahedron than the Platonic tetrahedron but still sufficiently symmetrical to be ...
Truncated triangular trapezohedron, also called Dürer's solid: Obtained by truncating two opposite corners of a cube or rhombohedron, this has six pentagon faces and two triangle faces. [27] Octagonal hosohedron: degenerate in Euclidean space, but can be realized spherically. Bricard octahedron with an antiparallelogram as its equator. The ...
The tetractys is an equidistant and equiangular arrangement of ten points inside a triangle, akin to the fourth triangle number. It was developed by Pythagoras, and collectively signifies cosmic unity in the form of The Decad, as well as the musica universalis, or collective abstraction of the music generated by heavenly cosmic bodies.
The regular complex polytope 4 {4} 2, , in has a real representation as a tesseract or 4-4 duoprism in 4-dimensional space. 4 {4} 2 has 16 vertices, and 8 4-edges. Its symmetry is 4 [4] 2, order 32. It also has a lower symmetry construction, , or 4 {}× 4 {}, with symmetry 4 [2] 4, order 16. This is the symmetry if the red and blue 4-edges are ...
One logo depicts a small heart surrounded by a larger heart, symbolizing a relationship between an pedophile and minor girl. Another logo resembles a butterfly and represents non-preferential ...
One is a regular tetrahedron, which is a triangular pyramid with four equilateral triangle-shaped faces. They are nicknamed caltrops, and are peculiar in that there is no topmost face when a die comes to rest. There are several common ways of indicating the value rolled. Some of these dice have three numbers on each face.
Those colored shapes are called “printer’s color blocks” or “process control patches,” and they’re there to help the printing team who prints the food packaging.
