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.
