proposition: Lemma rclo10_dist clo (MON: monotone10 clo) (DIST: forall r1 r2, clo (r1 \10/ r2) <10= (clo r1 \10/ clo r2)): forall r1 r2, rclo10 clo (r1 \10/ r2) <10= (rclo10 clo r1 \10/ rclo10 clo r2).
proof: Proof. intros. induction PR. + destruct IN; [left|right]; apply rclo10_base, H. + assert (REL: clo (rclo10 clo r1 \10/ rclo10 clo r2) x0 x1 x2 x3 x4 x5 x6 x7 x8 x9). { eapply MON. apply IN. apply H. } apply DIST in REL. destruct REL; [left|right]; apply rclo10_clo, H0. Qed.
