Proof step 2 from proof prefix-del-right (previous step)

⊦ st ⊑ st0 -- m ↔ st ⊑ st0 ∧ ¬ m ∈ st

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ st0 ⊑ st ↔ dom st0 ⊆ dom st ∧ (∀ n. n ∈ st0 ∧ n ∈ st → st0[n].list ⊑ st[n].list ∧ st0[n].ladrlist ⊑ st[n].ladrlist ∧ # st0[n].list = # st0[n].ladrlist ∧ # st[n].list = # st[n].ladrlist)
Proof step 4:
⊦ dom st ⊆ dom(st0 -- m) ∧ (∀ n. n ∈ st ∧ n ∈ st0 -- m → st[n].list ⊑ (st0 -- m)[n].list ∧ st[n].ladrlist ⊑ (st0 -- m)[n].ladrlist ∧ # st[n].list = # st[n].ladrlist ∧ # (st0 -- m)[n].list = # (st0 -- m)[n].ladrlist) ↔ st ⊑ st0 ∧ ¬ m ∈ st
