要　旨　：
　 　Recent developments of multi-strange nuclear physics are overviewed, highlighting the recent experimental and theoretical developments in Lambda-Lambda hypernuclei. By applying the exact treatment of few-body (three- and four-) quantum systems, we can assess the strength of the Lambda-Lambda interactions based on the world data of Lambda-Lambda hypernuclear binding energies, including those of recently observed Lambda-Lambda-4H and Lambda-Lambda-6He nuclei. The most clear event (Lambda-Lambda-6He) supports a one-boson-exchange soft core model (NSC97), and Faddeev calculations using the same interaction further suggest that Lambda-Xi-6He marks the onset of nuclear stability for Xi hyperons or the S = -3 world.
