This Demonstration gives a dissection of the rhombic hexecontahedron and of a rhombic-like solid that consists of 30 halves of the rhombic dodecahedron of the second kind put on a triacontahedron; the result is a combination of the icosidodecahedron and the rhomb-icosi-dodecahedron.

## Details

That such dissections exist follows from [1], where it is shown that certain combinations of Platonic and Archimedean solids have Dehn invariant 0.
