BP1192 Short, short, long, short, long vs. not.
(edit; present; nest [left/right]; search; history)
COMMENTS

All examples in this Problem are paths of short and long line segments which do not self-intersect. This could be a useful world to use in an abstract binary sequence BP.

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.
