However, if the Cartesian Product of two circles is the duocylinder, does that mean the Cartesian Product of two triangles is a duopyramid?
Is this the same as Rotope 55?
Moving on from that, what is Cartesian Product of two pyramids called (Rotope 188?)?
Do the 'Cartesian Squares' (in effect) follow a regular pattern or do each have to be considered on an individual basis?
This would lead onto a question regarding the use of indices/powers in generating higher dimensional figures, but I'll leave that for the moment...

Concatenation in rotopic group notation does NOT necessarily mean cartesian product, where tapering is involved.
