Proof step 33 from proof all-classes-02 (conclusion)

⊦ ∃ str. ∀ rk. rk ∈ rks ∧ is_fskey(rk .key) → # rk .key .fs .class .class < # str

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 32:
⊦ ∃ str. ∀ rk. rk ∈ rks ∧ is_fskey(rk .key) → ¬ # str ≤ # rk .key .fs .class .class
