The mass of the lowest spin-zero, strangeness-(−2) flavor singlet state in the dibaryon sector has been calculated in quenched QCD on 163×32 and 243×32 lattices at β=5.85 to study whether the energy of the proposed H dibaryon is near or below the ΛΛ threshold. Preliminary results indicate that finite lattice volume artifacts overestimate the binding, and that on the largest lattice mH is of the order of 100\MeV above the ΛΛ threshold.
