Superkleismic
Superkleismic is a regular temperament defined in the 7-limit such that three 6/5 generators reach 7/4 (tempering out S5/S6 = 875/864, the keema) and such that three 8/7 intervals reach 3/2 (tempering out S7/S8 = 1029/1024, the gamelisma), making it a member of the gamelismic clan and a keemic temperament. It extends extremely easily to the 11-limit as well, by tempering out S10 = 100/99 (as well as 385/384 and 441/440) so that two generators reach 16/11, which serves to extend the structure of orgone in the 2.7.11 subgroup. Since in superkleismic, the interval 21/20 stands for half 10/9 = 20/19 × 19/18, we can identify 21/20, 20/19, and 19/18 together to add prime 19, tempering out S19 = 361/360 and S20 = 400/399. Superkleismic can also be defined in the 13-limit, where two generators are identified with 13/9 alongside 16/11, tempering out 144/143 and 325/324.
The minor-third generator of superkleismic is ~6.3 cents sharp of pure 6/5, even wider than the kleismic minor third (~317 cents), and from this it derives its name. The two mappings unite at 15edo. While not as simple or accurate as kleismic in the 5-limit, it comes into its own as a 7- and 11-limit temperament, approximating both simply and accurately in good tunings. Discarding the harmonics 3 and 5 and concentrating purely on that subgroup gets you orgone. 41edo is a good tuning for superkleismic, with a minor-third generator of 11\41, and mosses of 11 (4L 7s), 15 (11L 4s), or 26 notes (15L 11s) are available.
