Construction of rhombic aproximate of Stewart toroid G3, together with construction of
rhombic aproximate of tridiminished icosahedron (rhombic triacontahedron),
shows that combination of these solids is equdecomposable with cube.

The same is true for the icosahedron and drilled G3.

So, the same is true for 3 icosahedra and drilled dodecahedron.
