We note that there is an explicit construction of (M)0,n as a blow up of Pn-3 along a sequence of simple centres (see(3.1)).In particular (M)0,5 is a del Pezzo of degree five,(M)0,6 is log Fano, and (M)0,7 is nearly log Fano,in the sense that -K)M)0.7 is effective.We do not know of such an explicit construction of (M)0,n, and we have in general a much weaker grasp on its geometry (though a much stronger grasp on its cones).Note by (1.3.3),(M)0,nadmits no nontrivial fibrafions.See also (3.7).
