Proof step 7 from proof save-load-save (previous step)

n < BRANCH_SIZE, m + nused ≤ BRANCH_SIZE, m ≤ n ⊦ save(load(save(zbrar, m, nused), m, nused), m, nused)[n] = save(zbrar, m, nused)[n]

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 8:
n < BRANCH_SIZE, m < BRANCH_SIZE, m ≤ n, m + nused ≤ BRANCH_SIZE ⊦ save(load(save(zbrar, m, nused), m, nused), m, nused)[n] = save(zbrar, m, nused)[n]

Rule argument

Used simplifier rules: fle-01: ⊦ m ≤ n ∧ n < n0 → m < n0; (forward) from specification nat
