Augmented, 12 & 15, is a 5-limit temperament generated by a 1\3 period (representing 5/4) and a 3/2 generator; it has MOS scales triwood (3L 3s) and tcherepnin (3L 6s). It tempers out 128/125, the difference between a stack of three 5/4s and the octave.

Because 128/125 = 126/125 * 64/63, Augmented admits a structurally induced 7-limit extension, called Augene, which adds Archy tempering to the fifth and provides sharp tunings for primes 3, 5, and 7. 15edo and 27edo are notable tunings of Augene.
