Proof step 5 from proof map-ifn-full (
previous step
)
⊦ ar.mapIndices(ar.indicesWhere(φ, # ar), f) = ar.mapIndices(ar.indicesWhere(φ), f)
User applied rule insert rewrite lemma
And obtained the following new goals
Proof step 6
:
⊦ ar.indicesWhere(φ) = ar.indicesWhere(φ, # ar)
Rule argument
spec: <toplevel> name: indiceswhere seq: ⊦ ar.indicesWhere(φ) = ar.indicesWhere(φ, # ar) subst: [φ, ar] → [φ, ar] flags: <all paths>
Additional information
Used terms: φ, ar
