BP865

The class of included examples is distractingly irrelevant to the solution vs. not so.

BP965

BP1105

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

	COMMENTS	`Left examples have keyword "distractingworld" on the OEBP.` `This is different than the kind of distraction mentioned at noisy, which means there are details that are irrelevant to the solution changing between examples.` `To label a BP "distractingworld" is to judge that the type of examples are more specific than should have been necessary to communicate the same general solution idea--this involves separating out which ideas are the nice ideas the BP really ought to have been about, and which ideas seem unimportant and irrelevant. On the other hand, to label a BP "noisy" is just to notice there are extra properties varying that are independent of the solution property.`
	CROSSREFS	`Distractingworld BPs are often arbitrary.` `Adjacent-numbered pages: BP860 BP861 BP862 BP863 BP864 * BP866 BP867 BP868 BP869 BP870`
	EXAMPLE	`BP1105 was created as an extreme example of this. All images in that BP show the same distractingly detailed background, irrelevant to the solution.`

Bongard Problems about sequences vs. other Bongard Problems.

BP926

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

	COMMENTS	`Zero, one, or two objects may technically form a sequence, but if ALL examples of a BP have zero, one, or two objects, we do not consider that BP to be about sequences.`
	CROSSREFS	`See BP929 for distinction between sequences of arbitrary length and sequences of fixed length (keywords "sequence" and "fixedsequence").` `Adjacent-numbered pages: BP923 BP924 BP925 BP926 BP927 * BP929 BP930 BP931 BP932 BP933`

Number of dots is a power of 2 vs. not so.

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

	COMMENTS	`Numbers of dots on the left can be obtained by repeatedly doubling 1 dot.` `Numbers of dots on the left are the number of corners of a cube in some dimension.`

	COMMENTS	`Zero is intentionally left out to avoid confusion (although it would fit right).`

BP994

Net corresponds to a solid that can tessellate 3D space vs. net does not correspond to a solid that can tessellate 3D space.

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

	COMMENTS	`More specifically these solids are polyhedra, and are often called "space-filling".` `There is ambiguity here regarding some nets that can be folded to make multiple different solids. For example EX8175 could correspond to a cuboid with a pyramid-like protrusion at each end, a protrusion at one end and an indent at the other, or 2 indents. Only the second of these options can tessellate 3D space. For clarity's sake examples like this are not sorted on either side.`
