Proof step 4 from proof lsleninv-1 (previous step)

⌜m0⌝ = leninv(nσ), stutf(nσ), ⌜m⌝ < # nσ, n < nσ[m], m0 ≤ n, m0 < nσ[m] ⊦

User applied rule constructor cut

And obtained the following new goals

Proof step 5:
m0 = 0, ⌜m0⌝ = leninv(nσ), stutf(nσ), ⌜m⌝ < # nσ, n < nσ[m], m0 ≤ n, m0 < nσ[m] ⊦
Proof step 9:
m0 = m1 +1, ⌜m0⌝ = leninv(nσ), stutf(nσ), ⌜m⌝ < # nσ, n < nσ[m], m0 ≤ n, m0 < nσ[m] ⊦

Rule argument

var: m0
