72 et 11-limit linear temperaments

I did the same thing as before, only this time calculating the
11-limit wedgie. I then calculated gens^(5/3) cents for the
corresponding 11-limit temperaments. The reason for the 5/3 is best
left to the argument about this by the Mullahs of Mathematics on the
math list.

Ennealimmal gets beaten up badly and now Miracle rules the roost.
This is not because there isn't a highly accurate extension to the
11-limit, but because this one isn't it. Second place is now held by
kleismic (19/72), Enneamiracle is closing in at third, and 29/72 is
not far behind in fourth place. Some new entries now appear: 31/72,
the 65+7 system, in fifth, and 5/72, the 43+29 system, in sixth,
trailed by 35/72, the 37+35 system, in seventh. Now I leave it to
Dave Keenan to explain why these rankings are a bunch of nonsense;
however I think once again the method proves its worth as a
temperament-finder.

If Joe wants to try something new, he might consider Enneamiracle, in
a scale of 27 notes consisting of three rows of 9-ets separated by
secors. He might also look at kleismic if he hasn't already.

I'm not going to be able to take this very seriously until you
address the concern I had with your 7-limit results.

I don't know whether it _is_ nonsense. It's certainly way better than
random. If you give us the number of generators required and the error
for each one (and explain what the numbers mean), then folks have a
chance to make up their own minds.

But one obvious bit of nonsense is the 10 significant digits in your
badness numbers. I'd say 2 is all we need.

I'm game, Gene! Please keep this stuff on tap for me for the day
when "miracles" are no longer happening! Thanks for the
investigations!!!

how about a diamond made out of miracle :) or a cross set with Enneamiracle :)

Now *that's* getting into *your* world, Kraig. It *definitely*
should be done, even if it's a limited set of "pure" ratios!

It's computer output, so rounding off would mean a little more work,
for no apparent gain.

I saw a posting about 13/72, which I answered, but that is all.

Graham Breed detailed that for us -- the 11-limit diamond in MIRACLE
requires a chain of 45 generators, and happens to pick up one of
Partch's 43-tone scales (within 3 cents, as George Secor pointed out).

The planar temperament resulting from taking the Cartesian or direct
product of Miracle with Ennealimmal is exactly along the lines of
something Gene would be interested in . . . Gene?

That was it. I was misled by your misleading table.
