CROSSREFS

BP152 is the same solution (with the sides switched), using connected shapes and without black filling.
BP1206 was created to be a slightly different version of this: "vertical axis of symmetry vs. no vertical axis of symmetry." (That less specific solution fits this Bongard Problem as well.)
Adjacent-numbered pages:
BP45 BP46 BP47 BP48 BP49 * BP51 BP52 BP53 BP54 BP55
