Lately, I have had posters change/generalize their questions on me. So I am half prepared to see cardinality replaced by some measure. I still think the argument works because of the shape of the covering set (it is false for non-convex sets, and I am unsure about general rectangles) for infinitely many rectangles.

This question only makes sense for finite S and in this case the set of possible $S_R$ is also finite. Any two rectangles with the same $S_R$ are equivalent for the purposes of this question. | |
