We have to consider all minimal (P,Q,R)-chains.
By forward instantiating [14] the rule E2(f1(w, w), x, y, z, f2(w, w), w) → E3(x, y, x, y, y, z, y, z, x, y, z, w) we obtained the following new rules:

E2(f1(x0, x0), f1(y_8, y_9), x2, f2(y_11, y_12), f2(x0, x0), x0) → E3(f1(y_8, y_9), x2, f1(y_8, y_9), x2, x2, f2(y_11, y_12), x2, f2(y_11, y_12), f1(y_8, y_9), x2, f2(y_11, y_12), x0)
