We present a study on ab-initio calculations of three-neutron correlators from Lattice QCD. We extend the method of baryon blocks to systems of three spacially displaced baryons. This allows the measurement of three-neutron p-wave correlators with total spin S = ¹/2 and ³/2. In addition, we use automatic code generation that has high flexibility and allows for easy inclusion of additional channels in the future while optimizing the evaluation of contractions. Our measurements were performed on a newly generated 96 × 48³ Clover-Wilson gauge field ensemble with m_π ≈ 370 MeV. We present preliminary results of our calculations of one pion and nucleon as well as two nucleon (2N) and three neutron (3n) correlators.
