  • Dodecahedron - Wikipedia
    A pyritohedron (or pentagonal dodecahedron) is a dodecahedron with pyritohedral symmetry T h Like the regular dodecahedron, it has twelve identical pentagonal faces, with three meeting in each of the 20 vertices
  • Pyritohedron - from Wolfram MathWorld
    A pyritohedron is an irregular dodecahedron composed of identical irregular pentagons The name "pyritohedron" derives from that fact that a common crystal form in pyrite has this shape
  • Pyritohedron - Polytope Wiki
    A pyritohedron is a variant of the dodecahedron with pyritohedral symmetry, constructed as the dual of the pyritohedral icosahedron It has 12 identical mirror-symmetric pentagons for faces, with 3 vertex types
  • Pyritohedron Dimensions and Whole-Number Volume
    The pyritohedron and its space-filling complement, the tetrakaidecahedron, have identical whole-number rational volumes whether measured in units of regular tetrahedron or cubes
  • 14 - pyritohedron - Department of Mathematics
    When cubes do their best to act like a regular dodecahedron, it's called a pyritohedron: This picture is from Steven Dutch's webpage on Building Isometric Crystals with Unit Cells, part of his website called Symmetry, Crystals and Polyhedra
  • PYRITOHEDRON Definition Meaning - Merriam-Webster
    The meaning of PYRITOHEDRON is a pentagonal dodecahedron that is a hemihedral form of the isometric system of crystalline symmetry common to pyrite
  • Definition of pyritohedron - Mindat. org
    An isometric closed crystal form of 12 faces, having the general symbol {hk0}, most commonly {210} Each face is an irregular pentagon The form is named after pyrite, which characteristically exhibits this crystal form
  • Tetrakaidecahedron and Pyritohedron - Paul Bourke
    The pyritohedron is similar to the dodecahedron in that it consists of entirely pentagonal faces, but differs in that the edge lengths are not all the same The name is derived from the pyrite crystal which has the same shape
  • Pyritohedron - Matematicas Visuales
    If you fold the six roofs of a regular dodecahedron into a cube there is an empty space This space can be filled with an irregular dodecahedron composed of identical irregular pentagons (a kind of pyritohedron)
