Proof step 13 from proof spawn-sat-rg-strnger (previous step)

□ Inpf = Inpf', Rton(0)(S', S''), ¬ Ry(0)(S', S''), GInv(S') → GInv(S'') ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 14:
⊦ Rton(n)(s, s0) ↔ (∀ m. m ≤ n → Ry(m)(s, s0))

Rule argument

spec: inst: name: rton-def seq: ⊦ Rton(n)(s, s0) ↔ (∀ m. m ≤ n → Ry(m)(s, s0)) subst: [s0, s, n] → [S'', S', 0] flags: rewrite, current

Additional information

Used simplifier rules: lez-01: ⊦ m ≤ 0 ↔ m = 0; from specification nat Used terms: S'', S', 0
