Proof step 16 from proof maxref-exists (previous step)

r0 < r2, r0 < r1, r < r2, r3 ∈ st0[r -- sk, val], ∀ r. ∃ r0. r < r0, ∀ r1. r1 ∈ st0 → r1 < r0 ⊦ r3 < r2, r < r0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 13:
⊦ r ∈ st[r0 -- sk, val] ↔ r = r0 ∨ r ∈ st
Proof step 15:
r0 < r2, r0 < r1, r < r2, r3 = r ∨ r3 ∈ st0, ∀ r. ∃ r0. r < r0, ∀ r1. r1 ∈ st0 → r1 < r0 ⊦ r3 < r2, r < r0

Rule argument

[crewrite-arg: instore-02 , F , [val, sk, r0, st, r] → [val, sk, r, st0, r3] ]
