A slower version of the formation from "DFF Demo Cave 2 (4 flies)" - top left

Although, this works without the second Η, I think it can still count since an extra Η is influenced by 1Η-2Ζ

 darkstoorm : this is in fact the formation "lifted f-vortex" ("dff demo cave 1", top-middle) with an extra Η which does not influence the other flies (although vice versa, the other flies do influence the extra Η).   
  
 Arno , in his very good article on dancing fly formations on his homepage forum, categorizes such a formation not as a seperate dff, but as the basic dff (in this case, the "lifted f-vortex with three flies) with extra fly/flies.  
  
if i'm not mistaken, then the "lifted f-vortex" was the formation which can be extended with arbitrarily many ΗΗΗ at the left side.  Arno  once made a cave about this with 100 or so ΗΗΗ accompanying the dff :d

for comparison: this dff here has a speed of 5 frames per step, and it's still 5 times faster than the "three busy bees" in dbd 23 cave g :d
