Proof step 1 from proof valid-vtbl-map-indices-erasing (conclusion)

⊦ ¬ dups(nx) ∧ valid-indices(wlar, nx) ∧ valid-vtbl(apebs, vols, wlar, m) ∧ indices-erasing(wlar, nx) → valid-vtbl(apebs, vols, wlar.mapIndices(nx, f), m)

System applied rule normalize

And obtained the following new goals

Proof step 2:
indices-erasing(wlar, nx), valid-indices(wlar, nx), valid-vtbl(apebs, vols, wlar, m) ⊦ dups(nx), valid-vtbl(apebs, vols, wlar.mapIndices(nx, f), m)

Proof step 1 from proof valid-vtbl-map-indices-erasing (conclusion)
