Voronoi defines a partition of the cone of positive semidefinite n-ary forms 2 , where n is the number of variables and dimension of the corresponding lattice. We define a non-rigidity degree of a lattice as the dimension of the L-type domain containing the lattice. We prove that the non-rigidity d
