We use the monopole-instanton ansatz for the dreibein and the spin connection. The equations of motion are solved. We point out a two dimensional solution with a vanishing action.7 pages, major conceptual changes were made, title has changedHigh Energy Physics - TheoryGeneral Relativity and Quantum Cosmologytext
