Looking at the CRF discovery page, I noticed that we still don't have enumerated various "multistory" polychora formed by gluing segmentochora and similar together in one axial direction.
With Stella and its automatical calculation of dichoral angles I should be able to do this as long as I have models for the various shapes.
Basically, there are two types of polychora that can work in this regard. One type are those that have flat "top" and "bottom" cells and can be stacked upon each other. These include prisms, (n,4)-duoprisms, cupolas and rotundas. Next, there are polychora that only have the "bottom" cell and their top is subdimensional -- these can be only used at the "end" of the resulting polychoron. These include pyramids, pseudopyramids, bicupolic rings, (n,3)-duoprisms and biantiprismatic rings. And there are probably some segmentochora that don't belong to any of these or that have more usable orientations.
There might be more, but these are the basic ones. Do we have a model archive somewhere, or at least the numbers for them? Or would I need to build models for all of these?
