Proof step 93 from proof spawn-sat-rg-strnger (previous step)

□ (Outf = Outf' ∧ Inpf = Inpf'), ¬ Gton(n0 + 1)(S, S'), Gr(n0 + 1)(S, S') ∨ Gton(n0)(S, S'), GInv(S) → GInv(S') ⊦ last, blocked

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 94:
⊦ Gton(n)(s, s0) ↔ (∃ m. m ≤ n ∧ Gr(m)(s, s0))
Proof step 95:
□ (Outf = Outf' ∧ Inpf = Inpf'), ∀ m. ¬(m ≤ n0 + 1 ∧ Gr(m)(S, S')), Gr(n0 + 1)(S, S') ∨ Gton(n0)(S, S'), GInv(S) → GInv(S') ⊦ blocked, last

Rule argument

spec: inst: name: gto-def seq: ⊦ Gton(n)(s, s0) ↔ (∃ m. m ≤ n ∧ Gr(m)(s, s0)) subst: [s0, s, n] → [S', S, n0 + 1] flags: rewrite, current
