We performed calculations of nuclear systems composed solely of Λ^* hyperons, aiming at exploring the possibility of existence of absolutely stable Λ^* matter. We considered Λ^* interaction strengths compatible with the Λ^*Λ^* binding energy BΛ^*Λ^* given by the KN interaction model by Yamazaki and Akaishi [1]. We found that the binding energy per Λ^* saturates at values well below 100 MeV for mass number A≥120. The Λ^* matter is thus highly unstable against strong interaction decay.
