Proof step 2 from proof same-subclasses-tdnameex-03 (previous step)

tdname+∃(str0, class0), same-subclasses(class0, str, str0) ⊦ tdname+∃(str, class0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ ¬ tdname+∃(str, class0) ∧ tdname+∃(str0, class0) ∧ class0 ≤ class → ¬ same-subclasses(class, str, str0)

Rule argument

[crewrite-arg: same-subclasses-tdnameex-01 , F , [str, class0, str0, class] → [str, class0, str0, class0] ]
