Proof step 3 from proof max-perm (previous step)

∀ ints0. perm(ints1, ints0) → max(ints1) = max(ints0), perm(i + ints1, ints0) ⊦ max(i + ints1) = max(ints0)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
perm(i ' + ints1, ints0), ∀ ints0. perm(ints1, ints0) → max(ints1) = max(ints0) ⊦ max(i ' + ints1) = max(ints0)

Rule argument

Additional information

Used simplifier rules: c: ⊦ i + ints = i ' + ints; from specification list[intlista]
