Proof step 5 from proof lsleninv-1 (previous step)

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

User applied rule constructor cut

And obtained the following new goals

Proof step 6:
m0 = 0, ⌜m0⌝ = leninv(nσ), m0 < nσ[m], ⌜m⌝ < # nσ, n < nσ[m], stutf(nσ), m0 ≤ n ⊦
Proof step 10:
m0 = m1 +1, ⌜m0⌝ = leninv(nσ), m0 < nσ[m], ⌜m⌝ < # nσ, n < nσ[m], stutf(nσ), m0 ≤ n ⊦

Rule argument

var: m0
