Proof step 2 from proof load-branches-last (previous step)

⊦ load(brar, m, nused + 1) = load(brar, m, nused)[m + nused, load(brar[m + nused])]

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ load(brar, m, nused + 1) = load(brar, m + 1, nused)[m, load(brar[m])]
Proof step 4:
⊦ load(brar, m + 1, nused)[m, load(brar[m])] = load(brar, m, nused)[m + nused, load(brar[m + nused])]

Rule argument

spec: <toplevel> name: load-branches-rec seq: ⊦ load(brar, m, nused + 1) = load(brar, m + 1, nused)[m, load(brar[m])] subst: [nused, m, brar] → [nused, m, brar] flags: <all paths>

Additional information

Used terms: nused, m, brar
