Sharing intervals with the 7-limit diamond

The scale consisting of all tetrads sharing an interval with the
7-limit diamond consists of 43 notes, but two of its steps are
2401/2400s. If we breed-reduce it, we get a 41-note scale with 18
otonal and 18 utonal tetrads, and 10 each quintads, which compares
favoribly to Ennealimmal[45]. Of course some of these are off by
2401/2400 if you want to worry about that, and of course you can temper.
