Proof step 7 from proof primes-perm (previous step)

perm(ints, ints0), ∀ i. i ∈ ints → prime(i), i ∈ ints0 ⊦ prime(i)

Heuristic quantifier closing applied rule all left

And closed the goal!

Rule argument

pos: left 2 terms: i

Additional information

Used simplifier rules: in: ⊦ i ∈ ints ∧ ¬ i ∈ ints0 → ¬ perm(ints0, ints); from specification list-perm[intlista] Used terms: i
