Proof step 2 from proof fwd-inv-iblock (previous step)

istore[n] = iblock, inv(istore), n ∈ istore ⊦ inv(iblock)

Heuristic simplifier applied rule simplifier

And closed the goal!

Rule argument

Additional information

Used simplifier rules: ⊦ n ∈ istore ∧ inv(istore) → (inv(istore[n]) ↔ true); (ss)
