I have solved now (as third person) the "24cell FT" with much more
twists (about 10 millions) than Nan and Andrey. So the log file is big:
90MB. I had to zip it before sending it to the 4D cubing group. My log
file <http://l.yimg.com/kq/static/images/yg/img/doc/zip.gif>

For me the "24call FT" is the most beautyful of these virtual 4D
twisting puzzles (and similars). It is the only regular convex 4D
polytope which has no equivalent in 4D. The face turning mode is the
most natural one. "24cell FT" is about 5 times more difficult to handle
than the 3x3x3x3 and less lengthy than the 120cell.

96 2C face centers, 96 3C edges and 96 2C face sides sofar and I’m
approaching the 50% of the puzzle. My move count is 390’000 and the
elapsed time 42h45. Nan has reached 54’000 moves and 9h25 for the whole.
And Andrey is even better. I will use estimated 1 Mio moves to finish. I
think that Nan and Andrey must use external computer program power and
advise or do extremely sophisticated setup’s. Is that so?

with 120-cell it looks not difficult at all - but the most interesting
things are still ahead :)

needed 8121 moves compared to the about 800 moves of Nan for the same
thing. This is a little bit frustrating but not enough to stop my
efforts. Now I tackle the 96 3C edges. I have already a 3 cycle. The
same 3 cycle executed 3 times gives a 3 cycle for the 2C face-sides.

  1. For 52 faces I needed 5300 moves. Replaying the log file of Nan I
    see that he used only about 750 moves for all faces. Most of his moves
    are dedicated to place the 2 colored face-corner elements different from
    the face elements (13’000 to 54’000).
