"Reduce" returns repeated solutions!

Hello mathgroup,


I would like to know why when I write:

Reduce[(x >= y \[Implies] 2x <= 3y) && Abs[x] < 5 && Abs[y] < 5, {x,
    y}, Integers]
I obtain repeated solutions.



I obtain a lot of solutions like: x == -4 && y == -3 ...

But many of them appear repeated.
In this case I obtain   x == -4 && y == -1    two times.

How do you "simplify" the list of solutions?

Thanks in advance.
