    The author of "a question on permutations of coefficients of polynomials" has edited their closed question and flagged asking a moderator to reopen it. Opinions?


    Still looks like gibberish to me. I wouldn't vote to reopen, even if I had a normal vote.


    Agreed. Also, what on earth happened to awllower's comment? I'm seeing it in some monospaced font.

    does it look to you like this?

    It does to me. I'm not sure how to describe it, but it is something that happens if I tried to type Latin alphabets with my keyboard in "Chinese mode". I think it has something to do with the encoding of the text also. (Of course, this may not be what the user did, but that's what it makes me think of when I see that font.)

    As I noted in situ, I've tried and failed to determine the questioner's intent, and the latest rewrite is not helpful. I can't help trying once more. Is the question this: determine all polynomials $p$ such that every polynomial obtained from $p$ by permuting the coefficients of $p$ has a root in common with $p$ (in some extension)? If that's the question, I think I can answer it.

    I don't use Chinese input methods on the computer (although I do on the iPod, since many Japanese kanji agree with traditional Chinese characters and handwriting input is very useful in Japan to decipher kanji I see written but don't yet know), but I do use Japanese inpute methods. One of them is called "full-width romaji" and it comes out looking like that.. So I think that Willie Wong's explanation is essentially correct.

    The question does not seem well thought through. It has a whiff of "what if we could do X?" without appreciating that X is a very rare and somewhat artificial phenomenon.

    @Willie, that text consists of latin characters in the so called Halfwidth and Fullwidth form Unicode block (the block U+FF00--FFE), as U+FF45 FULLWIDTH LATIN SMALL LETTER E, for example. They are used when typesetting Latin characters in a context where most of the text is CJK, so as not to break the nice uniform spacing of the environing text.

    Yes, the question is exactly as Gerry Myerson stated, and I just were trying to give it a reasonable background, though main of you do not think so.
    Then I am looking forward to the answer, thank you for reading the question.
    I will try to reduce the formulation of the question and make it more clear and explicit.

    @allower:why you do not edit the question in the form that Gerry Myerson stated it and asking next to be reopened . Since you agree on what your question is and as Gerry Myerson said he has an answer , wether the question will be reopened or not he can edit the answer added in his existing answer . Regards
    I regret to admit that I was overconfident in my earlier assertion that I could answer the question, but I do think that I could make a useful contribution toward an answer, if allower does as minasteris suggests.

    I have edited the question and received a well answer, while I am still looking forward to the answer possessed by Gerry Myerson.
    And the answer I received in fact solved the question entirely so that the answers are all proposed by the examples in the comments preceding it.
    In any case, thank you for paying attention.

    I understand the question now and find it nontrivial. I have voted to reopen.

    I think all that's needed for a happy ending is for Mark Bennet to submit his comment as an answer and then for awllower to accept it (and I have added this as a comment). Mark's comment included everything I was going to contribute, and more.
