We investigate the binding energy of six-quark systems with strangeness s = -3 under the constituent quark model in the framework of RGM. The single N Omega channel with spin S =2 and the single Delta Omega channel with spin S = 3 are considered, respectively. The results show that both two systems can form loosely bound states: the binding energies are ranged from 3.5-12.7 MeV for N Omega and 4.4-14.2 MeV for Delta Omega system, respectively.
