  We consider the experimental data on the production of strange Lambdas, and
multistrange baryons (Xi, Omega), and antibaryons, on nuclear targets, at the
energy region from SPS up to LHC, in the framework of the Quark-Gluon String
Model. One remarkable result of this analysis is the significant dependence on
the centrality of the collision of the experimental ratios bar(Xi)+/bar(Lambda)
and bar(Omega)+/bar(Lambda) ratios in heavy-ion collisions, at SPS energies.
