That's just a matter of semantics but anyway by this definition you can just say you're solving a puzzle on the quotient space of the supercube group. : ) (Then two cubes would be identified if they only differed in centre orientation so it would be a puzzle in that sense, albeit only for the 2x2x2 and 3x3x3.) I agree to a large extent with what Tyson said (about it not being a puzzle, at least for most of the people here). At least in the sense it is not a puzzle to solve it - but in the sense of the of the theory behind it, there's still a lot to know. Maybe that's not a puzzle though. > I thought the book sounded pretty crap.
