Each of the figues has four triangles (two on two opposite sides) and two irregular pentagons. Each of the pentagons has a facet bounded by four smaller triangles. In other words, the model has for faces twelve irregular (but congruent) pentagons, and a total of forty-eight small triangles and twenty-four larger triangles.
