Goldberg polyhedron

Convex polyhedron made from hexagons and pentagons.

3rd century BC Greek mathematician Euclid (holding calipers), as imagined by Raphael in this detail from The School of Athens (1509–1511)

A Goldberg polyhedron is a dual polyhedron of a geodesic sphere.

Volume rendering of Geodesic grid applied in atmosphere simulation using Global Cloud Resolving Model (GCRM). The combination of grid illustration and volume rendering of vorticity (yellow tubes). Note that for the purpose of clear illustration in the image, the grid is coarser than the actual one used to generate the vorticity.

Conway polyhedron notation

Used to describe polyhedra based on a seed polyhedron modified by various prefix operations.

This example chart shows how 11 new forms can be derived from the cube using 3 operations. The new polyhedra are shown as maps on the surface of the cube so the topological changes are more apparent. Vertices are marked in all forms with circles.

Operators in the triangular family can be used to produce the Goldberg polyhedra and geodesic polyhedra: see List of geodesic polyhedra and Goldberg polyhedra for formulas.

Goldberg–Coxeter construction

Graph operation defined on regular polyhedral graphs with degree 3 or 4.

The result <math>GC_{1,1}(G_0)</math>, after rearrangement
Embedding of the result (rhombic dodecahedron)

The GC construction can be thought of as subdividing the faces of a polyhedron with a lattice of triangular, square, or hexagonal polygons, possibly skewed with regards to the original face: it is an extension of concepts introduced by the Goldberg polyhedra and geodesic polyhedra.

Hexapentakis truncated icosahedron

Convex polyhedron constructed as an augmented truncated icosahedron.

Illustration of a convex set which looks somewhat like a deformed circle. The line segment, illustrated in black above, joining points x and y, lies completely within the set, illustrated in green. Since this is true for any potential locations of any two points within the above set, the set is convex.

It is geodesic polyhedron {3,5+}3,0, with pentavalent vertices separated by an edge-direct distance of 3 steps.

The satellite was shaped like a geodesic sphere about 3 ft in diameter, with its 76 reflective panels on the shape make it looks similar to a large disco ball.
