For a finite set of points spanning a projective space of dimension r sufficient conditions for the property (Ne,k) are established. Then we restrict ourselves to consider a set X of r + 3 points. The graded Betti numbers of X depend on the configuration of the points and are determined in many cases. In particular, we describe precisely how long the minimal free resolution of X is linear and we give a lower bound for the number of possible different minimal free resolutions of such X.
