A 19-note breed tempered diamond scale

I find four {2,5,7} diamond-type scales with no more than 19 notes to
the octave and at least six breed-tempered otonal tetrads. Only one of
these is convex, the scale resulting from taking all ratios of
[25, 12,5 175, 245, 1715, 2401] and reducing to the octave. If we TM
reduce this by 2401/2400, we get

1 49/48 15/14 8/7 7/6 6/5 49/40 5/4 4/3 7/5 10/7
3/2 8/5 49/30 5/3 12/7 7/4 28/15 49/25 2

This has five JI tetrads of each kind, plus one each of a
breed-tempered tetrad and a marvel tempered tetrad; putting that all
together gives
seven miracle tetrads of each kind. The miracle tempered version
is -13, -10, -8, -7, -6 -5, -3, -2, -1, 0, 1, 2, 3, 5, 6, 7, 8, 10, 13.

Here it is in both 72 and 612 edo:

Interesting -- this isn't a continuous chain.
