	COMMENTS	`Very similar to the less clearly-defined solution "tiles itself with infinitely many copies (different sizes allowed) vs. does not".` `The left hand side of this is a weaker condition than the left hand side of BP1241.`

Each attribute is shared by every group or none vs. some attribute is shared by exactly two groups

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

	COMMENTS	`Attributes are shading, shape, and number.` `There are always three groups.` `This problem is related to the card game Set.`

BP1142

Bongard Problems where there is no way to turn an example into any other sorted example by adding black OR white (not both) vs. Bongard Problems where some example can be altered in this way and remain sorted.

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

	COMMENTS	`Left-sorted problems have the keyword "finishedexamples" on the OEBP.` `The addition does not have to be slight.` `Left-sorted Problems usually have a very specific collection of examples, where the only images sorted all show the same type of object.` `Any Bongard Problem where all examples are one shape outline will be sorted left, and (almost) any Bongard Problem where all examples are one fill shape will be sorted right.`
	CROSSREFS	`See BP1144 for the version about both additions and erasures, and only slight changes are considered.` `See BP1167 for a stricter version, the condition that all examples have the same amount of black and white.` `Adjacent-numbered pages: BP1137 BP1138 BP1139 BP1140 BP1141 * BP1143 BP1144 BP1145 BP1146 BP1147`

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."`

Number of dots in the Nth box (from the left) is how many times the number (N - 1) appears in the whole diagram vs. not so.

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

	COMMENTS	`Left-sorted examples are sometimes called self-descriptive sequences.`
	CROSSREFS	`See BP1147 for a similar idea.` `BP1149 was inspired by this.` `Adjacent-numbered pages: BP1143 BP1144 BP1145 BP1146 BP1147 * BP1149 BP1150 BP1151 BP1152 BP1153`

BP1157

The order in which the objects in the top half are combined to make the object in the lower half matters vs. not so.

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

	COMMENTS	`Operations depicted in right-sorted examples are called "commutative".` `"Order matters" here means that if the objects in the top half were to switch places, the output would look different.`

	COMMENTS	`Bongard Problems sorted left obtain the keyword "viceversa" on the OEBP.`
	CROSSREFS	`Contrast the keyword notso.` `"Viceversa" BPs are often dual.` `The solution to a less-than/greater-than quantity comparison Bongard Problem (keyword spectrum) where the two sides divide the spectrum in half can be phrased as "closer to left end of spectrum than right end vs. vice versa." Whether this is a natural way to phrase the solution depends on the kind of quantity being compared.` `Here are some examples of spectra for which the "vice versa" phrasing tends to seem natural: left vs. right, up vs. down, black vs. white, higher quantity of [thing type 1] vs. higher quantity of [thing type 2].` `Adjacent-numbered pages: BP1157 BP1158 BP1159 BP1160 BP1161 * BP1163 BP1164 BP1165 BP1166 BP1167`
