Around the rhombicosidodecahedron, 2
If we add twelve regular icosahedra to the rhombicosidodecahedron, as we did in Around the rhombicosidodecahedron, 1, but we build then twelve regular dodecahedra on top, twenty intersecting icosidodecahedra fit exactly among them. The finished object would have this look:
If, instead of building the whole object, we do without an icosahedron, a dodecahedron, and five icosidodecahedra, we can place a pentagonal foot:
In the next construction, we don't add objects trying to fill the space. We seek, instead, a big surface around the rhombicosidodecahedron, in a similar way as when building the rhombitruncated icosidodecahedron. As this surface will not be able to support the weight of the object, we begin by building a strong foot for supporting the core rhombicosidodecahedron. Then, we build the protruding structures which will hold the surface, about the same as the branches of a tree hold its crown:
Around each «branch» we place ten pentagons, of which five share a vertex with one of each of the surrounding branches. In the following pictures, these sharing pentagons are red, the intermediate ones being yellow:
