Black shapes can be arranged such that they fit inside rectangular outline vs. not so.

(edit; present; nest [left/right]; search; history)

	COMMENTS	`There is a slight ambiguity here regarding whether a shape could be placed within another shape's hole. This is a question of how one perceives the Problem: are we sliding shapes around on a table in 2D or are we allowed to 'lift' them in 3D space?`
