Hi Ed,

Thanks f=
or your kind words :)  

I'm not aware of=
anyone having solved the 3^5 without macros yet, so there is room for a ne=
w first there. It's surely possible, though the puzzle is quite tedious eve=
n with macros!  We used to have a separate 3^4 Hall of Fame category f=
or the first no-macro solve but decided to remove it at some point... sort =
of pointless because macros are very accepted around here, part and parcel =
of solutions.  

Some have taken automati=
on further.  As you mentioned, Don wrote a program to solve Rubik's cu=
bes in any dimension. We've also discussed leveraging computers for the sho=
rtest solve competition, but that hasn't happened as far as I know, and so =
we haven't been forced into the debate of whether computer-assisted solves =
count. Someone should force us :)

One thing I love=
about MC4D is that I never will fully grok it, and if I have the energy/in=
terest, I can always pick out things I don't know to investigate. Writing t=
his now makes me think of one - I'm wondering what the href=3D"https://en.wikipedia.org/wiki/Center_(group_theory)">center&nb=
sp;of the 3^4 group is. For the Rubik's cube, it contains two elements: the=
identity and the superflip.  Another question is God's number for the=
3^4, which we may never know.

The solve routines =
in MC4D and MC5D are a sneaky magic trick btw. They aren't actually finding=
a proper solution like Don's program, but simply running the scramble file=
in reverse.  And regarding the singularity, I love a thought Melinda =
shared here once: maybe it has already happened and we just aren't aware!div>

I'll have to leave your questions about MC7D to the=
others to give a proper response (I haven't solved with it), but I gather =
that some find it a simpler interface because more of the mess of the proje=
ction can be hidden away.

Keep us posted on your 3=
^5 solve!

Roice,

Wow. I can't think of a more sophisticated word with which to=
respond, so "Wow!" will have to do for the moment. I looked at your links.=
Thank you. I'm wondering how much automation I'll want in my first MC5D so=
lution. Noting that some solvers took...quite a few twists, I see the appea=
l. Congratulations on being the first person to solve the 3^5, by the way.<=
br>
The romantic in me wants to solve the 3^5 with no macros, but the mo=
re I look around, the less likely that seems. Hmmm...what's the etiquette i=
n the community about incorporating macros? How much automation is permitte=
d for a person to be able to take credit for a solution?

Of course,=
there are challenges in developing effective and compact macros, as well a=
s in simply "eyeballing" one's way through. I'm not really in a hurry to fi=
nish the penteract, but I don't want to spend the rest of my life on it eit=
her. LOL. I still have a lot of questions on the tesseract, and find myself=
wondering just how much is actually known. Since people have written progr=
ams to solve the cube for any number of dimensions, one might assume that t=
he phenomenon has been fully "grokked."

Then again, there is the be=
auty of the process...

When I run the solve routines on MC4D (and MC=
5D), I am humbled by the computer's ability to generate solutions to highly=
complicated puzzles in such a short time. We're still a good ways from the=
singularity, too!

Incidentally Roice, I've looked at your web prese=
nce, and find your creations rather enchanting. Admittedly, I've only scrat=
ched the surface. I'm a longtime fan of computer graphics and animation, an=
d I fear that I'm susceptible to spending long sessions just gawking at you=
r oeuvre.

I hope to get started on MC5D by the end of the week.
W=
hat's the advantage, if any, of solving the 5D cube with MC7D? Is it cleare=
r? Is the interface better developed? I can certainly see doing the hexerac=
t with MC7D (why make another program?), but I don't know what criteria to =
apply when deciding which app to use?

At some point, I'd like to sol=
ve a puzzle no one has managed to, and add that knowledge to the community.=


Time to catch my breath.
