| Dec 20, 2014 at 10:23 | comment | added | ZeroG | The only niggle(albeit small) I see is that the smaller set that you construct might have repeated elements. For, e.g., $\frac{x_i}{2}$ could be equal to $\frac{x_i-x_j}{2}$. But we can prove that each element occurs at most twice and we can remove repeated elements. Also, the generator for odd and even will have exactly one different element and that would be $x_j$. | |
