[[7L 7s|7L+7s]]
14 tones (6+2+6)

temperament: [[whitewood]]

This scale has some unusual properties:
* it has only two modes
* either mode may be split in any of the three possible omnitetrachordal ways (9/8-4/3-4/3, 4/3-9/8-4/3, 4/3-4/3-9/8)
* it is its own dual (changing all L to s, and vice versa, gives the same scale)
* the (imperfect) tunings of 9/8 and 4/3 are independent of L/s ratio
