I'm resending this, as it seems to have been a victim of list downage.

Incidentally, I just noticed that this scale differs by just one pitch
from a just version of Fokker's 12-pitch 7-limit scale that Dave Keenan
recently rediscovered. The one pitch that differs is 35:32, which needs
to be changed to 9:8. This reduces the number of 7-limit consonances in
the JI version to 30 again, but the 31TET or 1/4-comma meantone versions
have 38.
