Pseudo-Erlich-symmetric-decatonic in Blackjack

Here's the closest I can find to an Erlich-symmetric-decatonic in
Blackjack, expressed as degrees of 72-EDO

0 7 14 23 30 37 42 49 58 65(72)
7 7 9 7 7 5 7 9 7 7

On a chain of 20 miracle generators it looks like
2 9 16 23 30 37 44 51 58 65 0 7 14 21 28 35 42 49 56 63 70
+--+--+--------+--+--+--+--+-----------+--+
5--------------7-----1-----------------3
1/3---------------1/1---1/7------------1/5
7-----1-----------------3-----------------9

So, you can see that it occurs at 7 positions in Blackjack (two of
which are a perfect fifth apart), but it only has 2 otonal and 2
utonal 7-limit tetrads and one otonal 1-3-7-9 tetrad.

So Paul, can you tell us what your adaptive decatonic is, in 72-EDO?
And what it looks like on a Miracle chain?
