Proof step 21 from proof reduce-unique (previous step)

t3 = S _ v4 _ v5 _ v6 ∧ t0 = v4 _ v6 _ (v5 _ v6) ∧ value(v4) ∧ value(v5) ∧ value(v6), C[t3] = C0[S _ v1 _ v2 _ v3], value(v1), value(v2), value(v3), context(C0), context(C) ⊦ C[t0] = C0[v1 _ v3 _ (v2 _ v3)]

And obtained the following new goals

Proof step 20:
C[S _ v4 _ v5 _ v6] = C0[S _ v1 _ v2 _ v3], value(v4), value(v5), value(v6), value(v1), value(v2), value(v3), context(C0), context(C) ⊦ C[v4 _ v6 _ (v5 _ v6)] = C0[v1 _ v3 _ (v2 _ v3)]
