And obtained the following new goals

Proof step 52:
⊦ Prton(n)(s) ↔ (∀ m. m ≤ n → Pr(m)(s))
Proof step 53:
[:Inpf, S, Outf | [PL ¬ GInv(S) ∨ ¬ Pr(n0 + 1)(S)] ∥ [PL true]], GInv(s), ∃ m. ¬(m ≤ n0 → Pr(m)(s)), ∀ m0. m0 ≤ n0 + 1 → Pr(m0)(s) ⊦ Gton(n0 + 1)(s, s0) ∧ GInv(s0) ∧ ( Rton(n0 + 1)(s0, S) ∧ GInv(S) → (Rton(n0 + 1)(S', S'') ∧ (GInv(S') → GInv(S''))) -+-> (last ⊃ Poton(n0 + 1)(S) ∧ GInv(S);Gton(n0 + 1)(S, S') ∧ ¬ blocked ∧ (GInv(S) → GInv(S'))))
