Proof step 4 from proof same-subclasses-contains-tdnameex-03 (conclusion)

⊦ tdname+∃(str0, class) ∧ ¬ tdname+∃(str, class) ∧ class ≤ class0 → ¬ same-subclasses-contains(class0, str, str0)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
class ≤ class0, tdname+∃(str0, class), same-subclasses-contains(class0, str, str0) ⊦ tdname+∃(str, class)
