Recently had an edit rejected... https://math.stackexchange.com/review/suggested-edits/923003
There was a typo in the original "2-cycles" should have been "3-cycles" which is a fairly big mistake given the subject of the question/answer and threw me off to begin with.
I edited it but was told to add more edited characters. So I also added a link to the wiki page that provided more information about Parity of Permutations.
However, it was rejected as "does not make the answer more accurate"... which it does.
And "does not improved readability" ... which it does.
If there was no 6 character limit on the edit it would have been approved and would have made the answer more correct.
It seems like I happened to get two people on bad days rejecting it because their comments make no sense to me. Maybe I could've ordered the last sentence better (or not added it at all) but initially I had no intention of adding it and only added it to get around the 6 character limit.
Surely, asking for updates would have been a much better and more useful response than a rejection that seems to have taken no thought about it into consideration?
