Proof step 29 from proof instore-addobj-rec (previous step)

∀ r, r1, class, class1, fis1, st. r = r1 ∨ (instore(r, class, fis0, addobj(r1, class1, fis1, st)) ↔ instore(r, class, fis0, st)) ⊦ r = r1, instore(r, class, fv ' + fis0, addobj(r1, class1, fis1, st)) ↔ instore(r, class, fv ' + fis0, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 16:
⊦ instore(r, class, fv ' + fis, st) ↔ (r -- fv .1) × fv .2 ∈ st ∧ instore(r, class, fis, st)
Proof step 28:
∀ r, r1, class, class1, fis1, st. r = r1 ∨ (instore(r, class, fis0, addobj(r1, class1, fis1, st)) ↔ instore(r, class, fis0, st)) ⊦ r = r1, (r -- fv .1) × fv .2 ∈ addobj(r1, class1, fis1, st) ∧ instore(r, class, fis0, addobj(r1, class1, fis1, st)) ↔ instore(r, class, fv ' + fis0, st)
