proposition: Lemma gpaco6_mon clo r r' rg rg' x0 x1 x2 x3 x4 x5 (IN: @gpaco6 clo r rg x0 x1 x2 x3 x4 x5) (LEr: r <6= r') (LErg: rg <6= rg'): @gpaco6 clo r' rg' x0 x1 x2 x3 x4 x5.
proof: Proof. destruct IN. econstructor. eapply rclo6_mon. apply IN. intros. destruct PR; [|right; apply LEr, H]. left. eapply paco6_mon. apply H. intros. destruct PR. - left. apply LErg, H0. - right. apply LEr, H0. Qed.
