Hi Terrie,

    Methinks Mr. Sunada would benefit from a course in crystallography. 

    The type of symmetry and ordered packing displayed by diamond is not
    peculiar to diamond at all, and is shared by a few other minerals.
    To be fair, Mr. Sunada appears to be a mathematician, not a
    mineralogist or crystallographer, but.....

    So does Galena or table salt, for that matter, and many others.
    Although, if you read the above statement carefully and think about
    it, it is nearly nonsense. Who edits these articles?
