(0,0,12,20)-deltahedron consisting of two parallel octagonal "lids" (containing 2 spheres connected to 5 rods and 2 spheres connected to 6 rods) that are connected as antiprisms and are vertically extended with enough layers so the two lids are 90° rotated.

It is completely rigid, and highly reminiscent of Alain Lobel's frames.
