BP1199 The only rectangles are the individual regions and the whole vs. there is some other rectangle made of rectangles.
(edit; present; nest [left/right]; search; history)
CROSSREFS

All of the examples fitting left here would fit right in BP1200 except for (1) a single rectangle, (2) two rectangles stacked vertically, or (3) two rectangles side by side horizontally.


All of the examples fitting left in BP1097 (re-styled) would fit right here (besides the two possible arrangements made up of just two rectangles, but those aren't shown there).


See BP1201 for the version with triangles.

COMMENTS

Another wording: "can be repeatedly broken along 'fault lines' to yield individual pieces vs not."
