Proof step 13 from proof nodups-perm (previous step)

nodups(A0), perm(A0, A1) ⊦ nodups(A1)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ perm(A, A0) ↔ # A = # A0 ∧ (∀ n. #oc(n, A, # A) = #oc(n, A0, # A0))

Rule argument

spec:array-perm inst:array_of_nat name:perm-def seq: ⊦ perm(A, A0) ↔ # A = # A0 ∧ (∀ n. #oc(n, A, # A) = #oc(n, A0, # A0)) subst:[A0, A] → [A1, A0] flags:rewrite
