Proof step 34 from proof newref-same (previous step)

∀ r. r ∈ st ↔ r ∈ st0 ⊦ newref(st) = newref(st0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ newref(st) = next(maxref(st))
Proof step 33:
∀ r. r ∈ st ↔ r ∈ st0 ⊦ next(maxref(st)) = newref(st0)

Rule argument

[crewrite-arg: newref-fun, F, [st] → [st]]
