  1. Oct 5, 2011 #1
    1. The problem statement, all variables and given/known data

    [PLAIN]http://img193.imageshack.us/img193/820/unledoxy.png [Broken]

    3. The attempt at a solution

    OKay I could interpret A as something like

    {{-...,-...}, {-1,-1}, {-1,-2}...{-1,1}....{1,-1}, {1,1}, {2,...}, {..., ...}}

    Just a lot of combinations of integers without 0

    I don't understand this

    (x,y)R(u,v) thing? WHy is it a point??

    Don't skip the elements like: {0,-1}, {0,-2}...{0,1},{0,2}...

    I doubt that you will get much flack when you ask about a "quotient set".
