Proof step 18 from proof newref-exists (previous step)

jvmref < r0, r < r1, jvmref < r1, ∀ r0. r0 ∈ st → r0 < r, ∀ r. ∃ r0. r < r0 ⊦ r < jvmref, newref(r1, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 12:
⊦ newref(r, st) ↔ r ≠ jvmref ∧ (∀ rk. rk ∈ st → rk .ref ≠ r)
Proof step 17:
jvmref < r0, r < r1, jvmref < r1, ∀ r0. r0 ∈ st → r0 < r, ∀ r. ∃ r0. r < r0 ⊦ r < jvmref, r1 ≠ jvmref ∧ (∀ rk. rk ∈ st → rk .ref ≠ r1)

Rule argument

[crewrite-arg: newref, F, [st, r] → [st, r1]]
