Our method features finite dimensionality of the coset manifold by letting the vacuum stability group be infinite. No decomposition of the symmetry group to its finite-dimensional subgroups is required. The expected result, i.e. Einstein-Cartan gravity, is finally obtained.12 pagesHigh Energy Physics - TheoryGeneral Relativity and Quantum Cosmologytext
