Subject: A circulating temperament with exact brats

The wolfish triad for this one, on the F#/Gb degree, has a 14/11 type
major third and sharp fifth. The brat is the only one not simple,
177/176, though perhaps that is good enough as an approximate 1 to help.
The rest of it is pretty normal, but with nice brats; aside from the 3/2 
(pure fifths) and 2 brats Wendel used, it has brats of 4. This is also
a useful number, with the associated beat ratios going 4, -1, -1/4, so
that we have only integers and inverse integers (which amounts to the
same thing.)
