+Axiom Ack0 : forall m : nat, Ack 0 m = S m.
+Axiom Ack1 : forall n : nat, Ack (S n) 0 = Ack n 1.
+Axiom Ack2 : forall n m : nat, Ack (S n) (S m) = Ack n (Ack (S n) m).

+Lemma ResAck0 : (Ack 2 2 = 7 -> False) -> False.
+Proof.

+  autorewrite with base0 in H using try (apply H; reflexivity).
+Qed.
