Proof step 23 from proof Comp-get-01 (conclusion)

⊦ getarray(r1, i1, j, st) ≠ getarray(r2, i2, j, st) → ¬ arraycomp(r1, i1, r2, i2, j, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ arraycomp(r1, i1, r2, i2, j, st) ↔ (∀ i. 0 ≤ i ∧ i < j → st[r1 -- (i1 + i) '] = st[r2 -- (i2 + i) '])
Proof step 22:
∀ i. ¬ i < 0 ∧ ¬ j ≤ i → st[r1 -- (i1 + i) '] = st[r2 -- (i2 + i) '] ⊦ getarray(r1, i1, j, st) = getarray(r2, i2, j, st)

Rule argument
