Thread: "Introduction"

Hi, I recently joined the MC4D group after solving the 3x3x3x3 and
thought I'd send an introduction message along the lines of those
submitted by other solvers.

My name is Chris Ahna. I live in the United States, specifically in a
town called Puyallup outside of Seattle in Washington state. I'm 25
years old and work as a computer programmer, first for Intel and now for
Microsoft. I've been working as a programmer since graduating from
Pacific Lutheran University where I studied math, computer science, and
physics. Outside of work I play competitive Scrabble, fool around with
Rubik's cubes, solve crossword puzzles, and go bowling.

I first saw MC4D about a year ago during a brief period where I spent a
lot of time solving Rubik's cubes. I was interested then but didn't
attempt a solve until getting back into Rubik's cubes late in 2007.

I know how to solve 3D Rubik's cubes of all different sizes, although
I'm pretty dang slow at all sizes compared to speedcubers. For example,
it usually takes me at least 90 seconds to do the 3x3x3 and at least 10
minutes to do the 5x5x5. I've made some progress toward learning the
CFOP method used by speedcubers, focusing on the version nicely
described at http://www.cubestation.co.uk. That said, I only know the
CFOP F2L algorithms and still solve the last layer using the basic
solution found at http://cubeland.free.fr.

To solve MC4D I designated one hyperface (blue) as the "top," the
opposite hyperface (green) as the "bottom," and the remaining hyperfaces
as the "middle."

I started by solving the first layer, i.e., all of the top hyperface and
all adjacent components of the middle hyperfaces. Next I solved the
second layer, i.e., the components of the middle hyperfaces adjacent to
neither the top nor the bottom hyperface. Solving the first two layers
in this manner took about 1000 twists and was done without macros and
with very minimal application of algorithms from the 3D cube solutions
mentioned above.

Finally I solved the last layer, i.e., all of the bottom hyperface and
all adjacent components of the middle hyperfaces. This was almost
entirely done using macros that applied different combinations of
straightforward generalizations of many of the PLL and OLL algorithms
from the two 3D cube solutions mentioned above. Viewing the bottom
hyperface like a 3x3x3, I solved the centers (two color pieces), then
the edges (three color pieces), and finally the corners (four color
pieces). Each group of pieces was solved by first permuting all of them
into the correct locations and then orienting them in place. Solving
the last layer in this manner took about 2000 twists and probably isn't
something I would have had the patience to complete without macros.

All in all, this took 3070 twists and lots of time, at least 20 hours
spread over many different days. This seems similar to my 3D cube
solutions in that it's slow and reliant on algorithms formulated by
others, however it was also eventually effective and a lot of fun to
figure out! :-)

Hello, my name is Marvin Castellon. I am 14 years old. I live in=20
Alexandria, Virginia and I joined soon after I soved the 3x3x3x3. The=20
first time I solved the 3x3x3x3 it took me 7732 twists. The second time=20
it was 2650 twists. I have also solved the 2x2x2x2, so far my best on=20
it is 324 twists.

I live in an apartment with my parents and my little brother, Jeremy. I=20

to Francis C. Hammond Middle School. Right now I am in the eighth grade=20
and I am about to graduate middle school. In school so far I hold every=20
rubik's record from the pocket cube (2x2x2), to all big cubes, to the=20
3x3x3x3.

Solving the 3x3x3x3 was the hardest puzzle I solved so far. It took me=20
pretty long considering I was using Roice's solution. Well I glad to=20

Hello, I solved the 3x3x3x3 a few days ago and after turning in my log
file Melinda asked me to introduce myself here.

My name is Oscar Lazo, and I live in Mexico. I study phisics and what
I most like is listening to some good music (although I rarely do).=20

I solved the cube using Roice's solution, and I must say it would have
been hard for me to solve it on my own, It was a 1053 move solution
and although Melinda said it was a rather short solution I still it
find a long way from the sub 300 record. I didn't use any macros since
I couldn't make them anyway (I find programing rather difficult).

I came across this puzzle from the wikipedia article on rubriks cube
and I said to myself I have to make this. It took me about a full week
of work during my vacations.

Spanish is my native language, and I find the lack of spanish guidance
for this cube shameful, so I have written a guide in spanish with
Roice's solution which I would like to post in a blog. I currently
have none but I would like to know if it's okay with Roice that I do
that of course giving all the deserved credit to him.

Also I noticed that in superliminal's page, in the link section,
somebody made (Melinda perhaps) the comment on what the words "qu=E9
mareo" meant, well they mean something like "what a dizziness" or
"this makes me dizzy" :) uderstandable enough. So speaking of spanish
I wonder if any people here speaks it.

I never got macros to work either. I never figured them out and found it
easier to do the moves by hand.

Hi Oscar,

Please feel free to use the solution guide for blogging a translation, or
however you see fit.

It was nice to hear the Rubiks wiki page brought you to our group :) I
don't know who initially added the MC4D info there, but I did recently
notice someone had removed all of it (booooo!). After tracking it down to a
change last November whose edit summary was nothing but "incorrect
statements" (which of course seemed unjustified to me), I added it back in
and so far it seems to have survived. I would contend it is quite relevant
to that page (as much so as other related puzzles getting discussed), so I'=
m
happy to find out it was beneficial in your case.

Take Care,

Roice

Welcome Craig!

That's a great introductory story.

As you already know, we figured out your problem which (for the benefit
of everyone else) turned out to be caused by poor handling of
potentially empty macro files. If anyone else is having similar
problems, please simply move or delete your macro file or get the latest
version which contains a fix for this situation.

It's also good to know that we have a colorblind user. Does this cause
you problems with any other parts of the UI? Also, if you do manage to
create a color file that works well for 8-colored puzzles, would you
please sent it to me? I'd love to see an example of what works best for you.

Regarding your mathematician friend who told you "where to go", I've had
similar reactions from some of my more mathematically inclined friends
as well, including recently my math professor uncle who first introduced
me to the original 3D puzzle! My guess is that the thought of a 4D
Rubik's cube strikes them with terror because they feel that they should
be able to figure it out and are worried that they may fail if they try.
Or perhaps they are afraid to spend any real time with it because
they're worried that they will feel compelled to solve it and that that
will require a lot of work.

One thing that I've done in attempting to calm people's fears is to
point out that there are lots of fun things that you can do with the
puzzle besides the full solve of the 3^4. The most natural challenge is
to learn to easily solve one random twist, and then perhaps two or more
random twists. These exercises are extremely helpful in learning to
understand 4D objects, or at least their 3D shadows.

MC4D version 4.0 now gives us some even better activities to offer:
Visualizations of a whole zoo of exotic and beautiful 4D objects, and
the ability to rotate them in 4D via shift-dragging. We left the
length-1 puzzles in the menu specifically for this purpose. If anyone
has additional ideas for understanding friend's fears of the puzzle, or
of ways to gently introduce them to our favorite puzzle, please share
them with us.

Congratulations on all your cube solutions, and good luck putting
together that exploded Lego factory that we call the 5^4!
-Melinda

Hello and welcome! Congratulations on your 4^4 and 5^4 solve. I just
finished my first 5^4 about an hour ago (isn't up yet) thinking I'd
land in the 13th spot ;-) You beat me by a few hours it seems. You
totally deserve it though, I can't imagine trying to solve colorblind.
I had so much trouble finding the colors in the edge triplet creation
phase.

I was planning on taking on the 6^4 but this one took me about 20 hours
so without piece finding and other aids I don' think I will.

Regards,

Brandon

Hi everybody,
It was suggested to me that I do a little introduction, so here it is. My n=
ame is Matt Ennis, and I'm a 16 year old from Connecticut. I'm still in hi=
gh school, but I plan to go to college to be a physics teacher after I grad=
uate.=20
I'm more of a puzzle collector that a speedcuber (although my 3x3 time is a=
round 23-25 seconds on a good day). I also do a lot of reading and I listen=
to a lot of music. I play the tube and trumpet, as well as a little piano,=
and I'm hoping to learn cello at some point.=20
That's about it, hope to see everyone around here,
Matt

Hi David :3

You're a 26 year old with a first experience with cubing at 6. What is time?

Even though you didn't get to make 3^4 algs, you still translated LBL it
seems onto the 3^4, and that's already something. I think at least half the
people on this group (including me) started with just following through
Roice's method (solution available on the webpage) for the whole thing.

The method in general seems clear, but I'm not sure how the second
layer/middle reel is solved. Since doing normal 3^3 algs on it moves 3x1
sticks, are the sticks first manually joined on the last layer then
inserted into the right place?

For the last layer, the twist of having to do cube move+twist+cube move
inverse is something I still credit Matthew for first telling me about.
I've written the process down on the superliminal wiki under the SZ method,
which is just a translation of the CFOP method into 4D.

Of course, if you're bored with not finding new algs, then try 3^5. x3
Ray
