Proof step 217 from proof kappa-RED1 (previous step)

〈RED1(t; tn2)〉 tn2 = tn0, ∀ n0, t, tn1, tn0. n0 < m + 1 → (〈RED1(t; tn2): n0 〉 tn2 = tn1 ∧ 〈RED1(t; tn2)〉 tn2 = tn0 ∧ tn0 ≠ tn1 → false), tn0 ≠ tn1, ¬ (tn1 = none ∧ ap(t)), tn3 = tn2, m ≠ 0, ap(t) ∧ ap(t .1) ∧ t .1 .1 = K ∧ value(t .1 .2) ∧ value(t .2), some(t .1 .2) = tn1 ⊦

And obtained the following new goals

Proof step 216:
〈RED1(t; tn3)〉 tn3 = tn0, ∀ n0, t, tn1, tn0. n0 < m + 1 → (〈RED1(t; tn3): n0 〉 tn3 = tn1 ∧ 〈RED1(t; tn3)〉 tn3 = tn0 ∧ tn0 ≠ tn1 → false), t .1 .1 = K, tn0 ≠ some(t .1 .2), m ≠ 0, ap(t), ap(t .1), value(t .1 .2), value(t .2) ⊦
