Even though lots of Λ-hypernuclei have been found and measured, multi-strangeness hypernuclei consisting of Ω are not yet discovered. The HAL QCD Collaboration in the lattice QCD simulations, have found attractive interaction in the ΩN^5 S_2 and ΩΩ^1 S_0 channels which support bound state with a central binding energy of 1.54 MeV and 1.6 MeV, respectively. Motivated by the above, in the present work, we study hypothetical multi-strangeness nucleus (_ΩΩ^6)He in the three-body ΩΩα system searching for deeply bound states or resonances which may be sought experimentally. We calculate the binding energy of the multi-strangeness system ΩΩα about 67 MeV. Also, we define the geometrical characteristics of (_ΩΩ^6)He ground state i.e. the different r.m.s. distances between the articles including the r.m.s. matter radius.
