The effects of adding the d${+\mathrm{}}^5$He cluster configuration to a formulation consisting of ${}_{}{}^3{}_{}{}^{}$H+α, n${+\mathrm{}}^6$Li, and n${+\mathrm{}}^6$${\mathrm{Li}}^{\mathrm{*}}$ cluster configurations are examined. The result shows that, because of the reduction effect of the Pauli principle, the improvement in the ${}_{}{}^3{}_{}{}^{}$H+α ground-state cluster separation energy and scattering phase shift is only moderate. On the other hand, the calculation also indicates that the deuteron spectroscopic factor in the ground state of ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$ is likely to have an appreciable magnitude, in agreement with experimental finding.
