  2. Dodecahedron - Wikipedia

    en.wikipedia.org/wiki/Dodecahedron

    The concave equilateral dodecahedron, called an endo-dodecahedron. [clarification needed] A cube can be divided into a pyritohedron by bisecting all the edges, and faces in alternate directions. A regular dodecahedron is an intermediate case with equal edge lengths. A rhombic dodecahedron is a degenerate case with the 6 crossedges reduced to ...

  3. Regular dodecahedron - Wikipedia

    en.wikipedia.org/wiki/Regular_dodecahedron

    A regular dodecahedron or pentagonal dodecahedron [notes 1] is a dodecahedron composed of regular pentagonal faces, three meeting at each vertex. It is an example of Platonic solids, described as cosmic stellation by Plato in his dialogues, and it was used as part of Solar System proposed by Johannes Kepler. However, the regular dodecahedron ...

    Measuring about 8 centimeters (3 inches) across, the dodecahedron is hollow and covered with 12 holes of varying sizes. The 1,700-year-old object will be displayed at the Lincoln Museum from May 4 ...

  5. Roman dodecahedron - Wikipedia

    en.wikipedia.org/wiki/Roman_dodecahedron

    A Roman dodecahedron or Gallo-Roman dodecahedron [1] [2] is a small hollow object made of copper alloy which has been cast into a regular dodecahedral shape with twelve flat pentagonal faces. Each face has a circular hole of varying diameter in the middle, the holes connecting to the hollow center, and each corner has a protruding knob. [ 1 ]

  7. Rhombicosidodecahedron - Wikipedia

    en.wikipedia.org/wiki/Rhombicosidodecahedron

    The rhombicosidodecahedron shares the vertex arrangement with the small stellated truncated dodecahedron, and with the uniform compounds of six or twelve pentagrammic prisms. The Zometool kits for making geodesic domes and other polyhedra use slotted balls as connectors. The balls are "expanded" rhombicosidodecahedra, with the squares replaced ...

  8. Dyakis dodecahedron - Wikipedia

    en.wikipedia.org/wiki/Dyakis_dodecahedron

    The dyakis dodecahedron can be constructed by enlarging 24 of the 48 faces of the disdyakis dodecahedron and is inscribed in the dyakis dodecahedron, [2] [page needed] thus it exists as a hemihedral form of it with indices {hkl}. [3] It can be constructed into two non-regular pentagonal dodecahedra, the pyritohedron and the tetartoid.

  9. Great dodecahemidodecahedron - Wikipedia

    en.wikipedia.org/wiki/Great_dodecahemidodecahedron

    Aside from the regular small stellated dodecahedron {5 / 2,5} and great stellated dodecahedron {5 / 2,3}, it is the only nonconvex uniform polyhedron whose faces are all non-convex regular polygons (star polygons), namely the star polygons {5 / 2} and {10 / 3}. It is a hemipolyhedron with 6 decagrammic faces passing through the model center.
