This is the keyword "dual" on the OEBP. See left-BP919 for artificially imposed duality.

Given an example there is some way to "flip sides" by altering it. The left-to-right and right-to-left transformations should be inverses.

It is not required that there only be one such transformation. For example, for many "handed" problems (left-BP552), flipping an example over any axis will reliably switch its sorting.

It is not required that every left example must have its corresponding right example uploaded on the OEBP nor vice versa.

Bongard Problems such that potential positive examples can be put in "natural" bijection with potential negative examples vs. other Bongard Problems.

Bongard Problems with "world" any image of a black bounded subset of 2D space vs. other Bongard Problems.

Assumed contained in bounding box (and thus has origin).

This world includes more complicated objects that are not plain "shapes" (left-BP792) such as fractals and parts of fractals. It should still be possible to parse what these pseudo-"shapes" are meant to be in context within the image. When part of the image looks self-similar up to high detail it is assumed to be self-similar (in the infinitely detailed sense).

Bongard Problems with "world" one simple connected black 2D shape (holes allowed) vs. other Bongard Problems.

Assumed contained in bounding box.
