Proof step 179 from proof same-subclasses-01 (previous step)

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

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ contains(str, ty, ty0) ↔ (∃ tys. contains(str, ty ' + (tys + ty0)))
Proof step 178:
same-subclasses-contains(class, str, str0), ∃ tys. contains(str0, mkclasstype(class) ' + (tys + mkclasstype(class0))) ⊦ tdname+∃(str, class0)

Rule argument

[crewrite-arg: contains-type-def , F , [ty0, ty, str] → [mkclasstype(class0), mkclasstype(class), str0] ]
