-In 5-limit 260edo has the same mapping as [[65edo]], and in 7-limit the same as [[130edo]].
+edo is [[enfactoring|enfactored]] in the [[7-limit]], with the same tuning as [[65edo]] in the 5-limit, and the same as [[130edo]] in the 7-limit. The mappings for [[harmonic]]s [[11/1|11]] and [[17/1|17]] differ, but 260edo's are hardly an improvement over 130edo's. [[29/1|29]] is the first harmonic that is offered as a sizeable improvement over 130edo. In the 2.3.5.7.29 subgroup, 260edo tempers out 841/840, 16820/16807, and 47096/46875.
