Subject: New 4^4 Record



Well I guess I'll announce this for myself this time.

I've just uploaded my revised solution to the 4^4. This solve was 1741
moves, which is 27 moves less than the previous record (not very much
less :p )

I'm glad Remi went back and beat my record, if he hadn't I don't think
I would have started with the hypercubes again.

Well, in order to shave off the 150 moves from my last solution I had
to go back and revise my method a little. A few experiments later, I
found a way. Something interesting to note is that I no longer use
most of Roice's sequences. In fact, the only sequences I used were the
3-colour edge flip and the 4-colour corner shuffle(twice). With these
changes, I fairly confident that I can consistently solve the 3^4 in
450-500 moves.
I'm thinking, if I have time in university, that I will write an
in-depth description of my (the Noel Chalmers) method so it can be
posted on the site, but that's for later.

I'm sure this record won't stand for very long, so once someone beats
it I'll return to the hypercubes to face to challenge.

Talk to you all later!

Whoops.

I guess I uploaded that file too early :)

I've just uploaded my new solution to the 4^4. This solution is 1714
twists, which is 54 twists shorter than the current record.

I think I got it right this time ;)

Look for me to upload my solution to the 5^4 using my new method. I'm
thinking it will be around 3220ish.

Later.

Well, MC4D says that your new solution has 1712 moves and not the 1714
you claimed so I updated the HOF with the shorter number.
Good work Noel. (And good luck beating it Remi!!) I notice that you
didn't use macros in your solution. Is that part of how you were able to
shave off a few twists here and there?
I'm looking forward your shorter 5^5 and a new solution description if
you ever do get the time to write that up.
