Proof step 8 from proof kappa-TOPRED (previous step)

〈TOPRED(t0 _ t1; tn2)〉 tn2 = tn0, t0 .1 = K, tn0 ≠ some(t0 .2), n ≠ 0, ap(t0), value(t0 .2), value(t1) ⊦

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 7:
〈TOPRED(t0 _ t1; tn2)〉 tn2 = tn0, t2 = K, tn0 ≠ some(t3), n ≠ 0, ap(t0), value(t3), value(t1), t0 = t2 _ t3 ⊦
