I decided to try the same idea on Porcupine[15] as I did on
Meantone[12], and came up with the following scale. It isn't supplied
with all the nice 9-limit harmony of meande, but it does have three
major tetrads, three minor tetrads, five major triads and five minor
triads, and a less traditional pattern of chord relationships.
