Proof step 4 from proof rangeeq-concrete-unfold (previous step)

⊦ range=(avol, n, avol0, n, m0 + 1) ↔ avol[n] = avol0[n] ∧ range=(avol, n + 1, avol0, n + 1, m0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
⊦ range=(avol, n0, avol0, n1, m + 1) ↔ avol[n0] = avol0[n1] ∧ range=(avol, n0 + 1, avol0, n1 + 1, m)

Rule argument

spec: array-splice, inst: avolume name: range-eq-rec seq: ⊦ range=(avol, n0, avol0, n1, m + 1) ↔ avol[n0] = avol0[n1] ∧ range=(avol, n0 + 1, avol0, n1 + 1, m) subst: [m, n1, avol0, n0, avol] → [m0, n, avol0, n, avol] flags: <all paths>
