Two new noble polyhedra - a new source of convex hulls to search from?

For general discussion of polyhedra, not necessarily Stella-specific.

In the meantime I found one more pair. It is derived from an augmented dodecahedron:

Is that different from the pair in my OP post? I can't see any difference

Oh, sorry, you're right, it's the same. I didn't look carefully.

Put together a very nice list of .stel files for the known nobles and special compounds (i.e. doubled-up facets and uniforms)

I'm trying to figure out a way to find 120-vertex noble polyhedra with stella.
Does anyone have any smart ideas?

I gave my computer another 16-GB memory and I got some noble 120-vertex-polyhedra but all of them were compounds. And in many other cases Stella crashes as before. I tried all uniform ones and their duals, the compounds of pairs of chiral 60-vertex noble polyhedra but I didn‘t find any distinct new one.
