=C2=A0=20
Hi Matt,
My move count was 54199. I know there's a big room to improve. My way of se=
parating permutations from orientations does incur large move counts. So, g=
ood luck on a shortest move solve!

Congrats Nan,
=C2=A0
I knew I wasn't gonna be fast enough to be the first one done, but I do hav=
e about 50% done and all algorithms ready. Having just got out of a particu=
larly difficult year of college (junior math/engineer double), I've been ha=
ving trouble dedicating enough time to sitting here nd solving it ;)
=C2=A0
Perhaps I can beat you in moves? ;) How many was yours?

As for the 120Cell, as I mentioned before, I believe it took me roughly 150=
hours, based on some random samples of how quickly I was solving pieces on=
average. I only used 2 permutation algorithms, very similar to eachother, =
and of only 8 and 12 moves and after doing them a couple of times, they eas=
ily become memorized. The actual process of clicking through the moves of t=
hese algorithms only took me about 16 seconds for the short one and about 3=
0 seconds for the second. Although I never memorized setup moves, it was si=
mple enough to abuse the undo feature to see exactly what setup moves I use=
d and remember them for the 10 seconds it took to redo back to the end of t=
he current solve. So my point here is that having the macros isn't as big o=
f a handicap as you may think. In fact, I've barely used any macros so far =
in my 24Cell solve. Especially in the beginning, they actually really hurt =
your flexibility in move count and setups.
=C2=A0
Congratulations again on the solve. You have too much free time and dedicat=
on!!! :D
Hopefully I'll be able to finish my solve and provide some great competitio=
n for lowest move count ;)

Hi,
Let me tell the story of solving the 24-cell. Everybody knows that 24-cell =
is much sexier than 16-cell. So after solving the 16-cell, I looked at the =
24-cell. There are only five types of pieces to solve in the 24-cell, compa=
red with eight types for the 16-cell. The 3-cycle algorithms are similar to=
the counterparts for the 16-cell. So it didn't take long to find them. Unl=
ike the 16-cell, I prepared many different rotation algorithms to fix the o=
rientations of corners and edges, so that whenever I need any of them, I ca=
n directly pull it off the shelf without thinking. I don't want to go into =
details because that would spoil the fun to those who wanna analyze it by t=
hemselves.
After I prepared all the algorithms, I still don't know if I can face the m=
ain difficulty of the 24-cell. The main difficulty is, of course, there are=
too many colors. This time I use shift+left, shift+right a lot. Basically =
I'm using them to find pieces. I never trust my color identification abilit=
y because there are too many close colors. I only claim two pieces have the=
same color when they are highlighted at the same time when I use shift+rig=
ht. In the beginning I wasn't sure if I could really handle 24 colors. So I=
used the first step, the face centers, as a test for me. The face centers =
don't need complicated algorithms. Finding pieces of certain color is every=
thing. I started the solve on Friday afternoon, when I finished the work I =
had to do for the week. I solved all the face centers intuitively. It meant=
that I could handle the colors.=20
After dinner I resumed the solve from about 9pm. By 2am, I solved all the p=
ieces except for the side-face pieces. I thought I should go on to finish i=
t, if the side-face pieces could be solved quickly. Then I used a stopwatch=
to time myself on solving one such piece. In that trial I was nervous and =
it took me 40 seconds to spot the colors, find the place it should go (usin=
g shift+right), setup, call the macro and reverse setup. A simple calculati=
on told me that I needed three more hours for all the pieces. So I gave up =
and went to bed. On Saturday I got up earlier than in weekdays and indeed s=
pent three more hours to finish it.
This one is my longest solve to date. There are six hundred pieces or so an=
d I can use macros. I really don't know how someone can solve the 120-cell =
without macros.
