Web2. máj 2003 · The 12 pentagonal units can be considered as fundamental for the construction of spherical species, such as C 60, the cluster of Bai et al. with their P 5 rings, the As 20 dodecahedron in the cluster of Moses et al., and Mo 132. They are abundant in the nearly spherical dodecahedron and in several Archimedean solids (see the figure).

WebThe dodecahedral space based on Poincaré’s idea was first given by Threfall and Seifert who characterized by the use of a dodecahedron the opposite faces of which are identified after a turn by π/5. It is called spherical because it is bounded by spherical pentagons due to the fact that it is obtained as the intersection of 12 balls. WebThe dodecahedron has two special orthogonal projections, centered, on vertices and pentagonal faces, correspond to the A 2 and H 2 Coxeter planes. In perspective projection, viewed above a pentagonal face, the dodecahedron can be seen as a linear-edged schlegel diagram, or stereographic projection as a spherical polyhedron.
