This is a compound of the icosidodecahedron and its dual, the rhombic triacontahedron. Notice how each vertex of one sits above a face of the other, and that edges from each cross at right-angles in pairs. The points where they cross lie on the shared midsphere of the two polyhedra, i.e. the edges are tangent to the midsphere at those points.

The model may be constructed in
**Great Stella**
by adding the icosidodecahedron to its dual via the menu item
"`Poly>Add Base Model and Dual`", or equivalently by going to the
compound of base & dual view, and clicking the left-and-down button
at the top of that view to use this compound as the new base model. Nets may
then be displayed and printed.

Some nets for the rhombic triacontahedron's pentagonal and triangular peaks.
