  The reaction $\Xi^-d\to n\Lambda\Lambda$ is studied within the framework of
the Faddeev equations as a possible tool to gain insight into the final state
$\Lambda$--$\Lambda$ interaction. The neutron differential energy spectrum
gives a final state interaction that is sensitive to both the
$\Lambda$--$\Lambda$ amplitude at threshold, and the coupling between the
$\Lambda$--$\Lambda$ and $\Xi$--$N$ channels. The latter is a result of
interference between two mechanisms for the production of the final state,
which suggests that this reaction could give a measure of flavor SU(3)
violation in the two-baryon system.
