Proof step 5 from proof same-subclasses-contains-trans (previous step)

same-subclasses(class0, str, str0), contains(str0, mkclasstype(class), mkclasstype(class0)), same-subclasses(class, str, str1), same-subclasses(class, str0, str1), same-subclasses(class, str, str0), contains(str1, mkclasstype(class), mkclasstype(class0)), same-subclasses(class0, str0, str1) ⊦ same-subclasses(class0, str, str1)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ same-subclasses(class, str, str0) ∧ same-subclasses(class, str0, str1) → same-subclasses(class, str, str1)

Rule argument
