See BP968 (flipped) for a version of this Bongard Problem including examples of invalid Bongard Problems that don't even admit a convoluted solution (the same image appears on both sides).

Also see BP1080, which is similar to BP968, but including various different formats of Bongard Problems, distinguishing them from arbitrary images that are not Bongard Problems.

Left examples have no solution, but they do not break the rules in ways so extreme that it is plainly impossible for them to have a solution, such as including the same image on both sides or including no images per side.

Left examples might be called "invalid," but often we instead use this term to mean "Bongard Problems" that break the rules in ways so extreme that they are no longer even Bongard Problems, such as including the same image on both sides or including no images per side. (See
