	COMMENTS	`Left-sorted BPs have the keyword "left-self" on the OEBP. Right-sorted BPs have the keyword "right-self."` `These keywords are added to pages automatically.` `Rhetorical questions: Where does this BP sort itself? Where does this BP sort the flipped version of itself?`
	CROSSREFS	`See BP793 for the version sorting pictures of Bongard Problems (miniproblems) instead of links to pages on the OEBP.` `See BP1075 for an example of a BP that is tagged "left-self" but would still be tagged "left-self" after the sides in the title were flipped. (This is unusual; a "left-self" BP after being flipped is typically "right-self" and vice versa.)` `Adjacent-numbered pages: BP512 BP513 BP514 BP515 BP516 * BP518 BP519 BP520 BP521 BP522`

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

	COMMENTS	`Left-sorted BPs have the keyword "left-full" on the OEBP.` `For meta-BPs about solution ideas, left-full only means the BP page hopes to include all fitting BP pages on the OEBP (as opposed to all possible Bongard Problems).` `As with applying the keywords left-finite and right-finite, deciding what should count as "different" examples depends on the Bongard Problem.` `Note this is not just BP574 (right-full) flipped.` `TODO: Maybe this should be changed into two keywords: one for non-meta-BPs and one for meta-BPs. - Aaron David Fairbanks, Feb 11 2021`
	CROSSREFS	`For non-meta BPs, left-full implies left-finite (at least until the OEBP implements a feature that allows algorithmic generation of infinite examples).` `Adjacent-numbered pages: BP568 BP569 BP570 BP571 BP572 * BP574 BP575 BP576 BP577 BP578`
