Comment (by vdelecroix):
Replying to [comment:15 zimmerma]:
> the new patch checks whether the product equals {{{(x1 - x2)*(x1 -
x3)*(x1 - x4)*(x2 - x3)*(x2 - x4)*(x3 - x4)}}} or its opposite.
Or you may modify the polynom to something invariant under permutation
{{{(x1 - x2)^2*(x1 - x3)^2*(x1 - x4)^2*(x2 - x3)^2*(x2 - x4)^2*(x3 -
x4)^2}}} (which makes sense as Jeroen pointed out, subset are not
ordered).
