Proof step 7 from proof lsleninv-1 (previous step)

leninv(nσ) = ⌜0⌝ , stutf(nσ), ⌜m⌝ < # nσ, n < nσ[m] ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: inst: name: leninv-zero seq: ⊦ stutf(nσ) → (leninv(nσ) = ⌜0⌝ ↔ nσ = ⌜λ n. 0⌝ ) subst: [nσ] → [nσ] flags: rewrite, current
