We study the quark-antiquark-gluon techniques in SU(3) lattice QCD, for different geometries, namely angles of 0, 45, 60, 90, 120, 135 and 180 degrees, between the quark-gluon and the antiquark-gluon segments. We calculate the form of the static potential and discuss whether, or not, two-body interactions exist between the three different bodies. We also study the existence of repulsion between the strings. We also mention the interactions between three gluon systems.
