proposition: Lemma graph_gen_ramif_stable: forall g gen, graph_has_gen g gen -> graph_rep g |-- generation_rep g gen * (generation_rep g gen -* graph_rep g).
proof: Proof. intros. unfold graph_rep. remember (nat_inc_list (length (g_gen (glabel g)))). apply iter_sepcon_ramif_stable_1. subst l. rewrite nat_inc_list_In_iff. assumption. Qed.
