Note that an icosidodecahedron, that is, the line graph of a dodecahedron, is a 4-regular planar graph without 4-cycles.
Next, for a disproof, imagine worlds whose only inhabitants can be simple geometric shapes of three kinds: dodecahedrons (dodecs), cubes, and tetrahedrons (tets).
These all have icosahedral symmetry and may be obtained as stellations of the dodecahedron and the icosahedron.
It can be seen as constructed from a rhombic dodecahedron elongated by a square prism.
Twelve of the 24 octahedral cells project in pairs onto six square dipyramids that meet at the center of the rhombic dodecahedron.
The remaining 12 octahedral cells project onto the 12 rhombic faces of the rhombic dodecahedron.
Although the desk is covered with ordinary objects, there is a metal dodecahedron that the reptiles climb over.
It also shares the same edge arrangement as the small stellated dodecahedron.
