  The orientifold planar equivalence is the equivalence in the large-N limit of
the bosonic sectors of the super Yang-Mills and the QCD with a quark in the
antisymmetric representation. I give a sketch of the proof of the orientifold
planar equivalence in the strong-coupling and large-mass phase on the lattice.
It is still matter of discussion, if its validity extends also in the continuum
limit.
