    The entry entitled (x, y) ⊙ (u, v) = (xu + 2yv, xv + yu) has been started. Is it Spam? or does that definition mean something useful to the nPOV.

    It’s the multiplication rule in [2]\mathbb{Q}[\sqrt{2}]. Maybe we should cross-link with field extension. :-)

    Of course, I should have thought of that, but surely that does not warrant a separate entry? We could use it as an example ;-)

    It also might be someone testing to see what symbols can appear in titles on pages (who doesn’t know that Doriath is the right place to do that.)

    Then again the IP 117.215.180.166 is somewhere in India so maybe someone is gearing up for a spam attack.

    (x, y) ⊙ (u, v) = (xu 2yv, xv yu) has been recreated. It probably needs emptying so as to discourage the activity that Rod mentions above. This one seems to be from Japan.
