Proof step 25 from proof exists-twonew (previous step)

∀ r. ∃ r0. r < r0 ⊦ ∃ r, r0. r ≠ r0 ∧ newref(r, st) ∧ newref(r0, st)

User applied rule insert lemma

And obtained the following new goals

Proof step 2:
⊦ ∃ r. jvmref < r ∧ (∀ r0. r0 ∈ st → r0 < r)
Proof step 24:
∃ r. jvmref < r ∧ (∀ r0. r0 ∈ st → r0 < r), ∀ r. ∃ r0. r < r0 ⊦ ∃ r, r0. r ≠ r0 ∧ newref(r, st) ∧ newref(r0, st)

Rule argument

[LEMMAARG : maxref-exists-01, [st] → [st]]
