In this work, we introduce an extension of the ab initio no-core shell model/resonating group method (NCSM/RGM) in order to describe three-body cluster states. We present results for the ⁶He ground state within a ⁴He+n+n cluster basis as well as first results for the phase shifts of different channels of the ⁴He+n+n system which provide information about low-lying resonances of this nucleus.
