The OBE-model potentials and quark-cluster-model (QCM) interactions are applied to study the structure of light S=-2 nuclei. We found that the OBE-model potentials predict a double-A hypernuclear state for the ground states of light S=-2 nuclei, while the QCM interaction with a bound H-dibaryon predicts a bound H-nuclear state, although the structure of the H-dibaryon state in a nucleus is significantly different from the free one. Fruitful experimental data will be highly desired to clarify the structure of S=-2 nuclei and hyperon mixing.
