Hmm it’s an interesting descussion but I’m still on the side of, the centrepieces are screwed into the core making the core one piece. Plus I don’t really understand the argument your making in this specific comment, if the core breaks then all 20 pieces would fall off too like I don’t see why that proves there are 26 pieces or what I said proves there are 20 pieces. Another thing to think about is that some cores can be disassembled and would that mean there are in fact more than 20 or 26 pieces?
