I added the following scale to the Gallery of 12-tone Just Intonation Scales on the xenwiki, so if Graham doesn't like it being called his scale now is the time to object.

This scale is interesting in part because though it has only 12 notes, it wants to be ragismic tempered, tempering out 4375/4374. Here's a ragismic version:

It has a major triad on 4, 5 and 10; a minor triad on 1, 2 and 9; a supermajor triad on 4, 10 and 11; and a subminor triad on 2, 7 and 9.
