  2. List of Wenninger polyhedron models - Wikipedia

    en.wikipedia.org/wiki/List_of_Wenninger...

    This is an indexed list of the uniform and stellated polyhedra from the book Polyhedron Models, by Magnus Wenninger. The book was written as a guide book to building polyhedra as physical models. It includes templates of face elements for construction and helpful hints in building, and also brief descriptions on the theory behind these shapes.

  3. Octahedral number - Wikipedia

    en.wikipedia.org/wiki/Octahedral_number

    The number of cubes in an octahedron formed by stacking centered squares is a centered octahedral number, the sum of two consecutive octahedral numbers. These numbers are These numbers are 1, 7, 25, 63, 129, 231, 377, 575, 833, 1159, 1561, 2047, 2625, ...

  4. List of uniform polyhedra - Wikipedia

    en.wikipedia.org/wiki/List_of_uniform_polyhedra

    The 5 Platonic solids are called a tetrahedron, hexahedron, octahedron, dodecahedron and icosahedron with 4, 6, 8, 12, and 20 sides respectively. The regular hexahedron is a cube . Table of polyhedra

  5. Octahedral symmetry - Wikipedia

    en.wikipedia.org/wiki/Octahedral_symmetry

    O h, *432, [4,3], or m3m of order 48 – achiral octahedral symmetry or full octahedral symmetry. This group has the same rotation axes as O, but with mirror planes, comprising both the mirror planes of T d and T h. This group is isomorphic to S 4.C 2, and is the full symmetry group of the cube and octahedron. It is the hyperoctahedral group ...

    Coxeter, Regular Polytopes (1963), Macmillan Company . Regular Polytopes, (3rd edition, 1973), Dover edition, ISBN 0-486-61480-8 (Table I: Regular Polytopes, (i) The nine regular polyhedra {p,q} in ordinary space)

  7. Rhombic dodecahedron - Wikipedia

    en.wikipedia.org/wiki/Rhombic_dodecahedron

    The non-regularity of these images are due to projective distortion; the facets of the 24-cell are regular octahedra in 4-space. This decomposition gives an interesting method for constructing the rhombic dodecahedron: cut a cube into six congruent square pyramids, and attach them to the faces of a second cube.

    The 5-fold projection is the main drawing on the right page. Max Brückner: Vielecke und Vielflache (1900) Colored as compound of five octahedra, with 3 great circles for each octahedron. The area in the black circles below corresponds to the frontal hemisphere of the spherical polyhedron.

  9. Jessen's icosahedron - Wikipedia

    en.wikipedia.org/wiki/Jessen's_icosahedron

    The convex shapes in this family range from the octahedron itself through the regular icosahedron to the cuboctahedron, with its square faces subdivided into two right triangles in a flat plane. Extending the range of the parameter past the proportion that gives the cuboctahedron produces non-convex shapes, including Jessen's icosahedron.
