Hi everyone,
I just solved the mighty 120-cell using Andrey's MPUlt. Note that the puzzl=
e definition was provided in a separate file
here
This solution took 54.5 hours and 78550 moves. I started this solution in t=
he beginning of June. After solving 3%, I suspended it because I was not su=
re that I wanted to do it now. Nine days ago, however, I determined to solv=
e it full throttle. So I solved 97% of the 120-cell in nine days (a whole w=
eek plus a weekend). Six hours per day on average. I am exhausted...=20
Comparing Roice's Magic 120-cell and Andrey's MPUlt, each has pro and con. =
Please correct me if I'm wrong. To the best of my knowledge, Roice's versio=
n has the piece-finding function, but no macros. Andrey's version has macro=
s, but no piece-finding function. I'm used to using macros so I chose Andre=
y's version. But I have to figure out some ways to find the pieces. Shift+r=
ight click can only highlight one cell at a time, and is not very helpful i=
n such a large puzzle.=20
My piece-finding method is: changing all cells to black and then the 3~4 st=
ickers on a piece to 3~4 colors. This way the destination of the piece is i=
mmediately visible. As a result, I spent more than half of my time changing=
the colors from black to color or from color to black.
Phew...

Awesome! Congratulations!

Nan,
Congratulations with the solve!
So far I solved only some 2C pieces of this puzzles, but my method is the=
following:=20
I select some face, change its color to white (by shift-right click), the=
n select some piece that has white sticker and is not at the white face. I =
highlight it (and always see where it's now), and move it to any free place=
at white face. Then I sort and reorient pieces at white face (change some =
other faces to white for this).=20

Hi Andrey,
I think your method is pretty interesting. Basically you need to first move=
a piece to the neighbors of the destination, and then correct it. The good=
thing about my method is that I can direct put a piece to the exact destin=
ation with the correct orientation at once. I don't know overall which one =
is more efficient, especially for 3C or 4C pieces.=20
Actually I just remembered that in the beginning I thought about using some=
methods similar to yours for 2C. I thought about solving a cell first and =
then expanding the solved region to more cells, which is more like a layer-=
by-layer approach. But I wanted to use 2C as an exercise and viability asse=
ssment for 3C and 4C. So eventually I chose to use the same method. After a=
few hours I felt the exercise was successful and enough. But at that time =
I couldn't switch to the layer-by-layer approach any more, because the solv=
ed 2C pieces were scattered in the puzzle rather than concentrated in an ar=
ea. Switching method means that I have to give up what I have solved. So I =
was actually stuck in that method.=20
I wonder how long have you used now. I used 14.5 hours when all 2C pieces w=
ere solved. I bet your solution must be faster.

I'm still somewhat shocked that several people have now solved this
beast. Not because it's hard but because of the shear size of the thing!
If I ever attempted it (which I will not), I suspect that I would have
tried the layer-by-layer method you describe. In this way you expand
outward in an ever growing (3D) circle as you work your way around a big
volume of 4-space, and then bring it down around the far side. I imagine
that the hardest part will be to close it completely, and that terrifies
me too. What I wonder is whether this method will give the solver some
sense of the 4-space volume and how the puzzle separates this finite
space from the infinite "outside". Would any of our solvers like to
comment on this thought?
