Proof step 4 from proof succlessleninv-invsize (previous step)

# nσ = ⌜inv(nσ)[n]⌝ + ⌜1⌝ , ⌜m⌝ = leninv(nσ), stutf(nσ), 1 + n < m ⊦ m = 0

User applied rule constructor cut

And obtained the following new goals

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

Rule argument

var: m
