Decatonic (in 72-tET)

I wish I would have prepared lattice drawings and full comments to publish
with these decatonic structures ib1183 and ib1215

<http://www.aei.ca/~plamothe/akar/decatonic.htm>

but I have to quit for few weeks or months.

Since these structures are closed related to temperament 72, I think
someone could be interested, even without any comment. (I used a scale with
36 divisions but it is easy to detect points on divisions and points
in-between).

The ib1183 structure is the minimal one corresponding to the Paul Erlich's
decatonic scales, as explained in "For all strict-JI fans . . ." at

/tuning/topicId_20642.html#20746

and the ib1215 is the minimal decatonic in non-degenerated 11-limit.

Since Monzo has opened a door about complexity notion, I would add soon a
new definition about complexity in a next message, before to quit.
