Some high JI approximations of the generator: 31/21, 34/23, 65/44, 71/48, 99/67, 105/71, 108/73, 133/90, 145/98, 176/119, 250/169. These could be used to guide the construction of neji versions of superdiatonic scales or edos. | Some high JI approximations of the generator: 31/21, 34/23, 65/44, 71/48, 99/67, 105/71, 108/73, 133/90, 145/98, 176/119, 250/169.

JKLMNOPQRJ = the symmetric Olympian mode (LLSLLLSLL), J = 261.6255653. &/@ = raise/lower by one chroma. | |||
Alternative standard: Extend the 7-note fifth chain FCGDAEB to a 9-note one, XFCGDAEBY. Use &/@ for the 7L 2s chroma. So the extended chain becomes ... B@ Y@ X F C G DA E B Y X& F& ... | |||
