I wonder if the latest edits in math.stackexchange.com/q/4729489/42969 (revisions 3, 4) should be reverted. They add a lot of stuff that was not present in the original question at all. Any opinions?
@MartinR Those additions were reverted by Carlos, but then added again. Edit wars should be avoided therefore we cannot revert it again. I have raised a moderator flag.
