Now clear and interesting finding! By _exhaustive_ do you mean Sage's native hyperplane arrangement or simply switching on the following `exhaustive` option? https://github.com/chenzhaiyu/abspy/blob/307d8575ac0d6544ddb637005372dec0d579010d/abspy/complex.py#L419

Sorry for the very late reply. I couldn't produce your result but I checked your results anchored here: > In fact, there seems to be a bigger problem with the...

I have currently no better way to dig deeper on this but one quick idea: the "components" might also be the result of non-manifoldness. For example, if two polytopes touch...

Hi @vedant41patel, this is an interesting usecase. The internal wall, though having points attached, is not part of the _boundary_: the two cells connected via this wall are both labeled...

You would first need to make sure a cell of the internal wall does exist in the cell complex, then perform the cut, and finally mark this cell as _inside_...
