A reflection can switch an object's sorting vs. not so.

(edit; present; nest [left/right]; search; history)

	COMMENTS	`In particular, horizontal reflections work in all left examples.` `An image of this Bongard Problem would fit on the left.`
	CROSSREFS	`See BP552 for the version with links to pages on the OEBP instead of images of Bongard Problems (miniproblems).` `Adjacent-numbered pages: BP866 BP867 BP868 BP869 BP870 * BP872 BP873 BP874 BP875 BP876`
	KEYWORD	`hard, abstract, challenge, meta (see left/right), miniproblems, creativeexamples, presentationmatters, infodense, assumesfamiliarity, structure`

Solution involves discrete quantity vs. solution involves continuous quantity.

(edit; present; nest [left/right]; search; history)

	CROSSREFS	`All examples in this Bongard Problem fit left in BP874.` `See BP351 for the version with sequences of constant change instead of Bongard Problems.` `See BP1152 for the version with links to pages on the OEBP instead of images of Bongard Problems (miniproblems).` `Adjacent-numbered pages: BP868 BP869 BP870 BP871 BP872 * BP874 BP875 BP876 BP877 BP878`

Bongard Problem would sort all relevant examples vs. possible objects similar to those seen on both sides would have no clear sorting.

(edit; present; nest [left/right]; search; history)

	COMMENTS	`Left examples partition a pool of objects cleanly into two classes.`
	CROSSREFS	`See BP509 (keyword "allsorted") for the version with links to pages on the OEBP instead of images of Bongard Problems.` `The left side implies BP876^left.` `Adjacent-numbered pages: BP870 BP871 BP872 BP873 BP874 * BP876 BP877 BP878 BP879 BP880`
	KEYWORD	`hard, challenge, meta (see left/right), miniproblems, creativeexamples, assumesfamiliarity, structure, presentationinvariant`

	AUTHOR	`Aaron David Fairbanks`

Precise sorting of potential examples vs. not so.

(edit; present; nest [left/right]; search; history)

	COMMENTS	`Left Bongard Problems do not have to sort all relevant examples; if they would leave some border cases unsorted, it just has to be clear precisely which examples those would be.` `Often a precise divide between values on a spectrum comes from intuitively "crossing a threshold." For example, there is an intuitive threshold between acute and obtuse angles. Two sides of a Bongard Problem on opposite ends of a threshold, coming close to it, are interpreted as having precise divide between sides, right up against that threshold.`
	CROSSREFS	`See BP508 for the version with links to pages on the OEBP instead of images of Bongard Problems.` `Adjacent-numbered pages: BP871 BP872 BP873 BP874 BP875 * BP877 BP878 BP879 BP880 BP881`
	KEYWORD	`hard, notso, challenge, meta (see left/right), miniproblems, creativeexamples, assumesfamiliarity, structure, presentationinvariant`

	AUTHOR	`Aaron David Fairbanks`

"Less than vs. greater than" (or vice versa) vs. "equal to vs. greater than" (or less than).

(edit; present; nest [left/right]; search; history)

	COMMENTS	`Left examples are quantity-comparison Problems in which the dividing point on the spectrum separating the sides lands between them. Right examples are quantity-comparison Problems in which the dividing point is the entirety of one of the sides (always the left side, for clarity).` `Only less-than vs. greater-than Problems may have imprecise (BP876^right) dividing point between sides.`

Some object(s) fit precisely between the sides vs. there is no object fitting between the sides.

(edit; present; nest [left/right]; search; history)

	COMMENTS	`"Allsorted" Bongard Problems (BP875^left) always fit as right examples.` `Left examples are never "allsorted".`
