The subgroup 2.9.15.7.11 is the [[11-limit|11-limit]] [[k*N_subgroups|2*11 subgroup]], the largest subgroup of the 11-limit on which [[11edo|11edo]] acts like [[22edo|22edo]], in the sense that it gives the same tuning to intervals and has the same commas. Oregon temperament is just 11-limit [[Porcupine_family|porcupine temperament]] restricted to this subgroup.
