	COMMENTS	`Left-sorted Problems usually have a very specific collection of examples, where the only images sorted all show the same type of object.`
	CROSSREFS	`See unstable vs. stable, which is about examples switching sides upon small changes instead of being rendered unsortable.` `See unstableworld vs. stableworld, which is about SOME small change to SOME example making it no longer fit in.` `See BP1142 for the version only about additions of detail (no erasures), and with no restriction on them being slight additions.` `Adjacent-numbered pages: BP1139 BP1140 BP1141 BP1142 BP1143 * BP1145 BP1146 BP1147 BP1148 BP1149`
