A rhombicosidodecahedron


From rhomb(ic) + icosidodecahedron, referring to the fact that the 30 square faces lie in the same planes as the 30 (rhombic) faces of the rhombic triacontahedron, which is dual to the icosidodecahedron.

rhombicosidodecahedron (plural rhombicosidodecahedra or rhombicosidodecahedrons)

  1. (geometry) An Archimedean solid with 62 regular faces (20 triangles, 30 squares and 12 pentagons), 60 vertices and 120 edges.

      The purpose of this article is to offer a method of approach for investigating the stellation pattern of the deltoidal hexecontahedron, the dual of the rhombicosidodecahedron.

      Next, the totality of 31 axes is illustrated in a rhombicosidodecahedron, an Archimedean solid composed of 30 squares, 20 triangles, and 12 pentagons (Fig. 33), with a view to the inside of the model showing the center of the group, the point of invariancy O (Fig. 34). [] Finally, the other dihedral subgroups are also illustrated on a rhombicosidodecahedron: D3 of order 6 and index 10 (Fig. 36) and D5 of order 10 and index 6 (Fig. 37).

      To finish, it needs to be clarified that the chosen figure, the rhombicosidodecahedron, composed of 62 flat sides as mentioned above, has five more units than the obtained landscapes.
