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?

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.)

Left-sorted Bongard Problems have the keyword "keyword" on the OEBP.

Left examples have the keyword "metaconcept" on the OEBP.

These are used under-the-hood by the OEBP system to display the concepts featured in a Bongard Problem; that is the main reason these pages exist.

"Metaconcept" implies sideless.

Adjacent-numbered pages:
BP514 BP515 BP516 BP517 BP518  *  BP520 BP521 BP522 BP523 BP524

This BP is a right example for itself because it does not indicate the presence of a particular concept in BP solutions.
