Proof step 17 from proof eval-term (conclusion)

r ∈ H, closed(H) ⊦ ⟪eval#(r, x, H; a?)⟫ true

Heuristic induction applied rule induction

And obtained the following new goals

Proof step 16:
∀ x0, r, H. # x0 < # x → r ∈ H ∧ closed(H) → ⟪eval#(r, x0, H; a?)⟫ true, r ∈ H, closed(H) ⊦ ⟪eval#(r, x, H; a?)⟫ true

Rule argument

indvar:# x wfpred:<
