We have built up the three-particle quantization condition on the lattice in a manifestly relativistic-invariant form by using a generalization of the non-relativistic effective field theory (NREFT) approach. The quantization condition can be applied to analyze 3-body lattice spectrum both in the center-of-mass frame and in moving frames. Correspondingly, quantization condition is projected onto octahedral group and its little subgroups. The translation from effective 3-body couplings to lattice spectrum has been carried in a toy model, therefore, inversely, the extraction of 3-body interaction from practical lattice spectrum can be done in the same formalism.
