Abstract An effective model is used to study the equation of state (EOS) of strange hadronic matter with nucleons,Λ-hyperons and Ξ-hyperons. In the calculation, a newest weak hyperon--hyperon (Y--Y) interaction deduced from the recent observation [Phys. Rev. Lett. 87(2001)212502-1] of a ⁶_ΛΛHe double hypernucleus is adopted.The calculated results are compared to those calculated with the strong Y-Y interaction used in previous studies.
