BP999

The collection of collections obeys the same rule as the individual collections vs. it does not.

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

	COMMENTS	`Rhetorical question: Where would the collection of left examples of this Bongard Problem be sorted by this Bongard Problem? (The question is whether these examples considered together satisfy the pattern that all the parts do, namely that the whole satisfies the pattern that all the parts do.)` `See BP793 and BP1004 for similar paradoxes.`
	CROSSREFS	`See BP1005 for the version about only numerical properties; examples in that BP would be sorted the same way here that they are there.` `See BP1003 for a similar idea. Rather than the collection of collections imitating the individual collections, BP1003 is about the total combined collection imitating the individual collections. A picture showing (for example) an odd number of even-numbered groups would be sorted differently by these two BPs.` `Also see BP1004, which is likewise about the whole satisfying the same rule as its parts, but there the parts don't themselves have to be collections; there the parts are just plain individual objects. The panels in BP999 (this BP) should be sorted the same way in BP1004.` `See BP1002, which is about only visual self-similarity instead of more general conceptual "self-similarity".` `Adjacent-numbered pages: BP994 BP995 BP996 BP997 BP998 * BP1000 BP1001 BP1002 BP1003 BP1004`

BP1145

Polygon that can be achieved by folding a square once vs. other polygons.

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

	COMMENTS	`Although it is tempting at first to make a version of this Bongard Problem with the solution "Shape can be achieved by folding a square a finite amount of times vs. other shapes", this alternate Bongard Problem would just amount to having the solution "Convex shape with straight edges vs. concave shape or convex shape with at least one curved edge."`
