(0,0,12,42)-deltahedron consisting of 2 hexagonal modules (containing 3 spheres connected to 5 rods) at the top and the bottom, and 6 more spheres connected to 5 rods around the middle. It is very similar to the (0,0,12,45)-deltahedron. The main difference is that the spheres connected to 5 rods around the middle are separated.

It is completely rigid, and highly reminiscent of Alain Lobel's frames.

It can be easily extended by introducing more layers.

Building Instructions Edit

  1. Create a hexagonal module with 3 spheres connected to 5 rods.
  2. Add layer after layer with spheres connected to 6 rods.
  3. Introduce a layer with 3 spheres connected to 5 rods (using the 3-fold symmetry of the structure so far.
  4. Introduce another layer with 3 spheres connected to 5 rods, so these spheres are separated to the ones in the previous layer by a sphere that is connected to 6 rods.
  5. Complete the bottom halve (notice that the top and bottom halve are identical).
