* Projection example: project2.ine
* Project on the 3-space (x1, x2, x3) by eliminating the last
* three variables (x4,x5,x6). The result is project2res.ine .
* This appears to be a very hard example to compute by
* the straighforward Fourier or Block elimination because they
* generate so many redundant inequalities.
