Wikipedia articles

My favorite ones to build:

• pentagonal antiprism, hexagonal antiprism, and such
• geodesic domes
  • icosahedron — all vertices have 5 edges [3d model] [wireframe]
  • pentakis dodecahedron — vertices have either 5 or 6 edges [3d model] [wireframe]

Things you can build without panels:

• all Platonic solids except for the cube and dodecahedron
• Antiprisms are all stable, and I like the "uniform n-gonal antiprisms".
• If you build a polyhedra from triangles only, then it will be stiff without needing panels. Mathematically, these are called "deltahedra" and "simplical polytopes". However, those include polytopes with legs of different lengths. Subsets of those that can be built with GeoMag:
  • bipyramids, e.g. the hexagonal bipyramid
  • do geodesic polyhedra work? (okay, these make my head hurt)
    • TODO: try this — pentakis dodecahedron [3d]

Things that require panels:

• of the Platonic solids — the cube and the dodecahedron
• Johnson solids
