Using the cascade code ARC to simulate relativistic heavy ion collisions at Brookhaven AGS energies (11.7--14.6 GeV/c), the authors have estimated the production rate of strange clusters ranging from a hypothetical doubly strange (S={minus}2) bound ({Lambda}{Lambda}){sub b} dibaryon to the hypernuclei {sub {Lambda}{Lambda}}{sup 6}He and {sub {Xi}{sup 0}{Lambda}{Lambda}}{sup 7}He. For the formation of multi-strange bound systems, high energy heavy ion collisions offer the only feasible method, since one can take advantage of the hyperons which are copiously produced in such collisions (typically 20 {Lambda}`s in a Au + Au central collision at the AGS) to form the composite object by coalescence.
