you're thinking about the minor third MOS, which also has 11 tones.

I've always thought that was a beautiful page Dave... have you thought
about this in terms of the 1/4 3/11, L/s = Phi mapping - the strictly
proper 4L7s generalized golden meantone?

Though I suppose you would have been thinking in terms of 26-tET and
not 19-tET had you wanted a strictly proper mapping in the first
place... they're definitely different animals as well, so maybe the
improper 19-tET mapping is ideal for what you wanted? Anyway, here's
the 1/4 4/15, L/s = Phi+1 stop on the journey to 4-tET:
