Proof step 23 from proof same-subclasses-contains-trans (previous step)

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

User applied rule cut formula

And obtained the following new goals

Proof step 13:
contains(str0, mkclasstype(class), mkclasstype(class0)), same-subclasses(class, str, str1), same-subclasses-contains(class, str0, str1), same-subclasses-contains(class, str, str0), contains(str1, mkclasstype(class), mkclasstype(class0)) ⊦ same-subclasses(class0, str, str1)
Proof step 22:
same-subclasses(class, str, str1), same-subclasses-contains(class, str0, str1), same-subclasses-contains(class, str, str0), contains(str1, mkclasstype(class), mkclasstype(class0)) ⊦ contains(str0, mkclasstype(class), mkclasstype(class0)), same-subclasses(class0, str, str1)

Rule argument

[fma-arg: contains(str0, mkclasstype(class), mkclasstype(class0))]
