Proof step 24 from proof ac-refin (previous step)

rk ∈ st, ∀ rk, st, class. rk ∈ st → rk ∈ addclass(class, fis0, st) ⊦ rk ∈ addclass(class, fv ' + fis0, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ is_fskey(fv .1) ∧ fv .1 .fs .class ≠ class → addclass(class, fv ' + fis, st) = addclass(class, fis, st)
Proof step 15:
¬ (is_fskey(fv .1) ∧ fv .1 .fs .class ≠ class), rk ∈ st, ∀ rk, st, class. rk ∈ st → rk ∈ addclass(class, fis0, st) ⊦ rk ∈ addclass(class, fv ' + fis0, st)
Proof step 23:
is_fskey(fv .1) ∧ fv .1 .fs .class ≠ class, rk ∈ st, ∀ rk, st, class. rk ∈ st → rk ∈ addclass(class, fis0, st) ⊦ rk ∈ addclass(class, fis0, st)

Rule argument

[crewrite-arg: ac-no1 , F , [st, fis, fv, class] → [st, fis0, fv, class] ]
