Subject: A 13-limit JI scale

I'm presenting this simply because I'm writing something in it. It is
irregular and has a lot of notes (41), but is useful because it has
fourteen complete 13-limit septads, 7 otonal and 7 utonal. It could be
tempered with (tempering out 10648/10647 is hardly likely to do any
damage, for instance) but I don't because the septads are all I need.

And a known one, it's a transposition of the 13-limit
Partch diamond.

I presumed it was likely to be a known stellated something or other, 
but Scala didn't tell me that. Is there I way I could have gotten it 
to?

Thanks for the info!

I used the compare command. Another slightly crude way is
"iter/key lat/diam" and looking if you see a filled square.
