Proof step 4 from proof prefix-refl (previous step)

inv(st) ⊦ dom st ⊆ dom st ∧ (∀ n. n ∈ st ∧ n ∈ st → st[n].list ⊑ st[n].list ∧ st[n].ladrlist ⊑ st[n].ladrlist ∧ # st[n].list = # st[n].ladrlist ∧ # st[n].list = # st[n].ladrlist)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
n ∈ st, ∀ n. n ∈ st → # st[n].list = # st[n].ladrlist ∧ inv-flashsize(st[n].list, st[n].ladrlist) ∧ ¬ dups(st[n].ladrlist) ⊦ # st[n].list = # st[n].ladrlist

Rule argument
