The 35 hexominoes and the 82 hexhexes can be made up from marbels. Since the straight piece is in both sets we have 116 different pieces.
In the plane three hexagons can be connected by two rectangles so that the hexominoes contribute some spheres at the edges of the hexagons. This is an example for a symmetric figure with changing grid structure. A solution is here.
The favoured objects to construct with polyspheres are pyramides. Three square pyramides of size 8x8 and one tetrahedron of size 7 can be constructed with the set. The solution showing the layers of each pyramide is here. For the numbering of the pieces and the construction of two roofs look at the polysphere section of my site.
