Proof step 18 from proof orderedls-all (previous step)

a < a0, (a0 ' + y)[m] < a0, ordered<(a0 ' + y), m ≤ # y, ∀ m0, n0. m0 < n0 ∧ ¬ # y < n0 → (a0 ' + y)[m0] < (a0 ' + y)[n0] ⊦ a < (a0 ' + y)[m]

User applied rule constructor cut

And obtained the following new goals

Proof step 19:
m = m1 +1, (a0 ' + y)[m] < a0, a < a0, ordered<(a0 ' + y), m ≤ # y, ∀ m0, n0. m0 < n0 ∧ ¬ # y < n0 → (a0 ' + y)[m0] < (a0 ' + y)[n0] ⊦ a < (a0 ' + y)[m]

Rule argument

var: m
