(0,0,12,8)- consisting of 3 hexagonal modules (containing 4 spheres connected to 5 rods). Another way of looking at this is the way the spheres connected to 5 rods are distributed over the surface of the deltahedron in between the spheres that are connected to 6 rods. In this case they form 3 clusters of 4 spheres, organised as two back-to-back triangles. It is completely rigid, and highly reminiscent of Alain Lobel's frames.
