Hi Jeremy,
I think 4D puzzles are an interesting crossing ground between spatial and
symbolic. I find that some people are better with spatial reasoning, and
others with symbolic reasoning. Roughly speaking, the former group are
usually better at geometry, and the latter at algebra.
I don't really know anything about the brain, but I'm just speaking from my
experience as a physics / math major and physics PhD student, and I find a
very clear distinction between these types of people. In my research, there
are many concepts and data-sets that can be viewed either graphically or
algebraically. My lab-mate strictly prefers the algebra. He wants to see
what functional form fits the data and work with the formulas. I much
prefer to plot my data as a set of contour surfaces in 3D and rotate it
around in a graphical interface. My lab-mate's way is usually better since
it is still not convenient to communicate science in a 3D manner since
publishers are still married to printed text on some level, although
hopefully that is changing.
4D puzzles take most spatial reasoning types beyond what they can actually
picture in their mind, and requires them to systematize spatial information
and think about it in a symbolic way. Maybe this could be related to the
"purpose" of 4D puzzles.
Best,
David

Hello and welcome!
I like your recursive representation. I *think* it is the same that Don
Hatch used in his n-dimensional cube solver.
http://www.plunk.org/~hatch/MagicCubeNdSolve/
Check out the docs of that here. His 3^4 looks the same as yours, and he
also has a 3^5 example.
http://www.plunk.org/~hatch/MagicCubeNdSolve/javadoc/
On the question of moves... Yes, limiting to the "simple" 90 degree twists
is enough to reach any position of the puzzles. The extra freedom allowed
in higher dimensions by twists that are not aligned with the coordinate
axes are interesting, but they don't increase the state space of the
puzzles.
Cheers,
Roice

Hello all,
I'm also new to this group. The MC7D program is not t=
he only appropriate way to visualise a 3^7-Rubik's cube, so you might u=
nderstand this one (which I hope is equivalent) better. I attached a bitmap=
picture showing a different method not doubling labels; each non-white pix=
el stands for one label and vice versa. It is constructed iteratively: To i=
ncrease dimension by one, the pattern is repeated three times and then &quo=
t;front" (with respect to the new dimension) and "back" labe=
ls are added. Start pattern is raster-2.png, in which each of the little sq=
uares is a label. If you combine two of these steps by arranging 3x3 patter=
ns and then adding "left", "right" resp. "top"=
;, "bottom" labels, you don't fill a line but a plain, thus o=
btaining a more compact representation (see raster-4.png for the image of a=
3x3x3x3-Cube after one double step).
By the way, the pictures were =
generated by a program, which I extended to execute moves on the cube, so I=
use this opportunity to put a question to this group, too. My program only=
allows "simple" moves: At first, one third of the cubies is sele=
cted by fixing one coordinate to be 1 or (-1); then two different coordinat=
es x_i and x_j are chosen and every selected cubie is rotated in the (x_i, =
x_j) plane, only changing its x_i and x_j coordinate. I hope that this is e=
nough to execute all possible moves by combining simple moves, for any dime=
nsion? Please inform me if I'm incorrect or if I have to be more specif=
ic.
By the way: The above iteration puts pixels into the plain such =
that any bounded region receives pixels until a certain dimension is reache=
d, and then it is fixed. By noticing that the way of entering moves describ=
ed in the previous paragraph does not depend on the total number of dimensi=
ons handled by the program, it can be regarded as "arbitrarily-dimensi=
onal Rubik's cube simulator".
Kind regards!
