Proof step 3 from proof prefix-append-notin (previous step)

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 ⊦ n ∈ st, st0 ⊑ st[n, ablock]

And obtained the following new goals

Proof step 4:
⊦ 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 5:
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 ⊦ n ∈ st, dom st0 ⊆ dom st[n, ablock] ∧ (∀ n0. n0 ∈ st0 ∧ n0 ∈ st[n, ablock] → st0[n0].list ⊑ st[n, ablock][n0].list ∧ st0[n0].ladrlist ⊑ st[n, ablock][n0].ladrlist ∧ # st0[n0].list = # st0[n0].ladrlist ∧ # st[n, ablock][n0].list = # st[n, ablock][n0].ladrlist)
