On the non-rationality of the Fano variety of ℙ5, which contains three planes two by two meeting in one point
We prove that the Fano variety W of degree 6 in ℙ5, complete intersection of a smooth quadric hypersurface with a smooth cubic hypersurface of ℙ5, is not rational if it contains 3 planes two by two meeting at least in one point.
