Proof step 153 from proof kappa-RED1 (previous step)

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