Proof step 238 from proof kappa-RED1 (previous step)

〈TOPRED(S _ t4 _ t3 _ t1; tn)〉 tn = none, 〈RED1(t1; tn4)〉 tn4 = tn5, 〈RED1(S _ t4 _ t3; tn2)〉 tn2 = none, ∀ n0, t, tn1, tn0. n0 < m + 1 → (〈RED1(t; tn3): n0 〉 tn3 = tn1 ∧ 〈RED1(t; tn3)〉 tn3 = tn0 ∧ tn0 ≠ tn1 → false), m ≠ 0, tn5 ≠ none, S _ t4 _ t3 _ t0 ≠ t4 _ t1 _ (t3 _ t1), value(t4), value(t3), value(t1), value(S _ t4 _ t3), tn5 = some(t0) ⊦

Proof step 237:
〈TOPRED(S _ t4 _ t3 _ t1; tn)〉 tn = none, 〈RED1(t1; tn4)〉 tn4 = some(t0), 〈RED1(S _ t4 _ t3; tn2)〉 tn2 = none, ∀ n0, t, tn1, tn0. n0 < m + 1 → (〈RED1(t; tn3): n0 〉 tn3 = tn1 ∧ 〈RED1(t; tn3)〉 tn3 = tn0 ∧ tn0 ≠ tn1 → false), m ≠ 0, S _ t4 _ t3 _ t0 ≠ t4 _ t1 _ (t3 _ t1), value(t4), value(t3), value(t1), value(S _ t4 _ t3) ⊦
