Orgonia
The Orgonia is a collection of temperaments of different ranks, including subgroup temperaments, that all temper out the orgonisma.

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