Note: I don't know if those are actual formations, but the last one is interesting!

also here, the first one must be a new dff with a short loop of 9 frames and moving up. the other three have a short loop of 5 so these could again be extended versions of known dff. the last, static one could be a new dancing fly stagnation.  
  
so you have found at least 2 new dff! congrat, that's pretty cool :d

Nice! :D it was a good experiment, pretty much bruteforced  7, 8, 9, 10 flies in various ways, I was later only looking at formations where __all__ flies had at least one interaction and it they repeated after more than 5 frames, so no idea how many potential formations I have missed :D I mostly started from boxes I saw in other caves, e.g. 5x3, 5x4, 6x5 and reversed

I ALSO PRETTY MUCH FORGOT HOW THAT WORKED, SO SOME TESTS DIDN'T pass, like two fireflies that have no interaction with spinning 4 butterflies

analysis so far:  
  
| formation 1 is indeed a new dff, congrat! :d it will be discussed on  Arno 's forum, of course!  
  
| formation 2 is a "lifted Η-vortex" (ΗΗΖ) with a free-riding formation (ΗΗΗ), and a separate "lifted Ζ-vortex" (ΖΖΗ) which doesn't interact with the rest. so it's actually not really a 9-fly formation.  
  
| same goes for formation 3; this is a "lifted Ζ-vortex" (ΖΖΗ) with a free riding 3-fly formation (ΖΗΗ) plus another free rider (Η). the other two ΗΗ form a separate "Η&Η".

formation 4 is very interesting; it's a "lifted Η-vortex" with 6 free-riding flies which temporarily build two more "lifted Η-vortices". a high level of mutual influences in this one! no new dff, though.

finally, formation 5 (the static one) is a brand new dfs, and a very special one because there are no spinning flies involved; every fly is influenced by the others. so far, the only dfs of this type had been  Arno 's "static-Ζ7". this one could be called "static-mix8" or "static-Ζ4Η4"!  
  
all in all, these are fantastic results! it's really high time to update  Arno 's thread in the forum. i'm going to compile all the new results and then let's revive that forum thread! :d

very cool, glad you likes them!  
  
I think I could probably find some more "by accident" by changing some parameters. So far I was only looking for formations where all flies interacted at least once after a short loop, which I kept increasing from 4 to 8 then 20 (most likely too extreme), so I was only comparing the formations after this many scans, I didn't really know how many scans I should give the formation to settle.  
  
My approach was comparing only the fly positions, I ignored their type and directions so I only had numbers to work with instead of objects to squeeze some extra performance. Still, I was just bruteforcing random spawns without storing them, so I just ran my program for 500_000 times with 200 max scans per formation, everything 60 times in parallel (around 2 minutes for full run), so at that point I didn't really care for colliding initial formations, I just printed out the results and checked in the CKit.  
  
It was a fun experiment, I definitely didn't do this correctly as I just wanted to see this working. I also forgot what was the longest loop that you use to verify the formation, I think it was 40, but I just played with the numbers :D  
  
Most of the results were just same formations at different stage5 :D

correction on formation 3:  
the Η&Η is not separate. it is a lifted Ζ-vortex and a Η&Η with 3+1 free riders.
