a demo cave of 7-fly dff:s consisting of 7Η (4) and 5Η+2Ζ (10). there's also one 7Ζ ddf which is not shown here but is introduced in "a nest of 7 fflies". it's the only 7Ζ dff. the two slowest dff:s of 5Η+2Ζ dff:s are also already introduced in "a race of slow 7-fly dff:s".  
   
the dff:s on this cave are raw formations meaning that all found formations are shown including already known formations with one or more freeriders.  
   
i'm pretty sure these are all possible 7Η and 5Η+2Ζ formations. i'm not 100% sure though; The search uses 6x6 window meaning that if any of the formation's states fits in the 6x6 box it will be caught in the search. also isolation heuristics is used to quickly discard some candidate formations. in theory there could be another dff which is so scretched that it always is bigger that 6x6 and has lots of isolated groups in its states so the search misses it. maybe i'll later do 7x7 search to verify the results.  
  
i'll check the remaining 7-fly combos in the near future. not in very near future though because i'm away from my main computer a few weeks :)  
  
dff statistics (short loop / long loop, dir) from left to right:

wow, great! i think a part of my weekend is now filled with the analysis of those :d  
  
also, it's very striking that all these formations move up. ΗΗΗ seem to have a very strong tendency to move up, especially in big groups. i note that not only in dffs, but also in classic ΗΗΗ-ΘΘΘ caves when i don't lead the ΗΗΗ properly to the ΘΘΘ. if they move away from the path i created for them, they almost always move upwards in big swarms! :d

results on the 7Η formations:  
1-3: each is a Η&Η with a 5ΗΗΗΗΗ- free riding formation.  
4: 2 Η&Ηs with a 3ΗΗΗ- free riding formation.  
all these formations are new discoveries afaik! :d

 nesdori , one question about the thrid formation of the 5Η2Ζ:  
  
if you remove the top-left Η (which is a single free rider), you get a 6-fly formation - a lifted Ζ-vortex formed by the ΖΖ and the new top-left Η, plus a 3ΗΗΗ free riding formation. afaik, this whole dff hasn't been published yet.  
  
now that confuses me because i thought that we were already through with 6-fly formations?! has this one been published already and i overlooked it? or if this is actually a new one, are there more unpublished 6-fly dffs? this would be very nice to know; i was already about to write on  Arno 's forum thread that we can be almost certain to know all 6-fly dffs with the help of computers! :d

 dustin , that formation is included in my list of 2Ζ+4Η dff:s (there are three 2Ζ+4Η raw dff:s). maybe it wasn't that interesting earlier because it's not unique but it's a known dff with free riders?

 dustin , .. and that formation also is introduced in my "new 6-fly dff:s" cave with some simple analysis :)

 nesdori : ah yes, indeed! that was my oversight, thanks :d  
good that i noted that before publishing the article :d

ALSO, I FINISHED MY ANALYSIS OF THE 5Η2Ζ FORMATIONS:  
  
1 = LIFTED Ζ-VORTEX WITH 5 "FLYING KITES"  
  
2,4,5,6 = 4 VERSIONS OF A Η&Β WITH A ΖΖΗΗΗ-FREE RIDER FORMATION, WHERE THE ΖΖ SWITCH PLACES AFTER A SHORT LOOP. ONE OF THE ΖΖ ALWAYS HAS THE ROLE OF THE "DANCING RIVAL" IN A LIFTED Η-VORTEX FORMATION. SO THE ΖΖ ARE RIVALS ABOUT WHO CAN BE THE RIVAL OF A ΗΗ COUPLE! :D  
I THINK THAT "RIVALING RIVALS" WOULD BE A NICE NAME FOR THESE FORMATIONS :D  
  
3 = LIFTED Ζ-VORTEX + 3Η (AS DISCUSSED) + 1 "FLYING KITE"  
7 = VERSION OF 3 WITH EXTRA Η (INSTEAD OF THE FLYING KITE). THIS EXTRA Η SWITCHES PLACES WITH ONE OF THE OTHER FREE RIDERS, SO TECHNICALLY THIS IS LIFTED Ζ-VORTEX + A 4Η FREE RIDING FORMATION..  
  
8 = the could-or-could-not-be-a-new-unique-dff formation which  darkstoorm  recently published ("funny flies collection", 3rd formation, see also my comment there).   
  
9 = "the tourist" (DFF)  
10 = "three busy bees" + 1Η free riding (actually, i haven't properly checked yet if it is technically really a free rider.)  
  
thanks for these formations,  nesdori ! i really have to make an overview with all the new "lifted Ζ/Η vortex" free riding formations before writing an article about them :d
