Proof step 11 from proof add-isobj (previous step)

⊦ r = r0, is_obj(r0, class, sks, addarray(r, ty, vals, st)) ↔ is_obj(r0, class, sks, st)

User applied rule induction

And obtained the following new goals

Proof step 10:
true, ∀ st, ty, sks, class, r0, r, vals0. # vals0 < # vals → (true → r = r0 ∨ (is_obj(r0, class, sks, addarray(r, ty, vals0, st)) ↔ is_obj(r0, class, sks, st))) ⊦ r = r0 ∨ (is_obj(r0, class, sks, addarray(r, ty, vals, st)) ↔ is_obj(r0, class, sks, st))

Rule argument

[INDHYPARG : [STANDARDINDUCTIONTYPE : ], true, false, # vals, [] → [], <]
