Convex closure of eikosany

Here's the ever-popular Eikosany scale:

tonic)

Here's a 7-limit version, made by using 384/35 in place of 11 (385/384
approximating):

And here is the above, tuned to 140-et, which tempers out 385/384 and
also (which turns out to be useful) 5120/5103:

The above "Ikosany" scale has 24 fifths, 12 major thirds, 12 7/4s, 7
11/8s and 4 13/8s, all in the 140-et tuning. Presented for whatever
it is worth; the tonality diamond would be another obvious starting
point for this.
