The infrared limit of the lattice Landau gauge gluon propagator is studied. We show that the lattice data are compatible with the pure power law (q(2))(2 kappa) solution of the Dyson-Schwinger equations. Using various lattice volumes, the infinite volume limit for the exponent kappa is measured. Although, the results allow kappa=0.498-0.525, the lattice data favor kappa similar to 0.52, which would imply a vanishing zero momentum gluon propagator.
