The lattice three-gluon vertex in the Landau gauge is
revisited using a large physical volume ∼(8fm)^4 and a large statistical
ensemble. The improved calculation explores the symmetries of the
hypercubic lattice to reduce the statistical uncertainties and to
address the evaluation of the lattice artefacts. In particular we focus
on the low energy behaviour of the vertex and look at evidences for (or
not for) a change of sign and its relation with ghost dominance.
