Proof step 309 from proof kappa-RED1 (previous step)

〈skip〉 tn3 = tn1, 〈TOPRED(t; tn2): n -1 〉 tn2 = tn3, 〈RED1(t; tn)〉 tn = tn0, ∀ n0, t, tn1, tn0. n0 < n → (〈RED1(t; tn): n0 〉 tn = tn1 ∧ 〈RED1(t; tn)〉 tn = tn0 ∧ tn0 ≠ tn1 → false), tn0 ≠ tn1, tn2 = tn, n ≠ 0, ¬ (tn3 = none ∧ ap(t)) ⊦

Heuristic symbolic execution applied rule skip left

And obtained the following new goals

Proof step 308:
〈TOPRED(t; tn2): n -1 〉 tn2 = tn3, 〈RED1(t; tn)〉 tn = tn0, ∀ n0, t, tn1, tn0. n0 < n → (〈RED1(t; tn): n0 〉 tn = tn1 ∧ 〈RED1(t; tn)〉 tn = tn0 ∧ tn0 ≠ tn1 → false), tn0 ≠ tn1, tn2 = tn, n ≠ 0, ¬ (tn3 = none ∧ ap(t)), tn3 = tn1 ⊦
