Proof step 15 from proof newref-newreflist-subset (conclusion)

⊦ r ∈ newref_list(n, st) ∧ st0 ⊆ st → newref(r, st0)

User applied rule structural induction

And obtained the following new goals

Proof step 1:
⊦ newref_list(0, st) = []
Proof step 14:
∀ r, st, st0. r ∈ newref_list(m, st) ∧ st0 ⊆ st → newref(r, st0) ⊦ r ∈ newref_list(m +1, st) ∧ st0 ⊆ st → newref(r, st0)

Rule argument
