Try (R U R' F)x5. It flips six edges 1,3,4,5,6,9

At Jared's request:
4x4x4 supercube: (UFR UFL) (Ufr Ufl)
Alg: U (Rr)2 (Bb)2 (Rr) F (Rr)' (Bb)2 (Rr) F' D' f' D F2 D' f D F2 (Rr) L F' L' f' L F L' f

This is 26 turns counting written turns in the alg. There must be a shorter way to do this. Anyone have any ideas? I think it would be more interesting to allow the more general case of finding an alg that swaps any two corners and any two x-centers on a 4x4x4 supercube. I'll keep looking into it as well.

Lw2 U2 r' U2 l U2 l' U2 (x) U2 l' U2 (Lw' R')

Nice execution in that one, it swaps opposite edges (parity).


----------

I have a look at your case Chris... ... ... or I would if I new your notation, (Rr) is that the same as Rw? I got a messed cube after doing them like that??

Tried it again, it was me, not your notation, got it the second time ^^

Hmm, maybe modify some R-PLLs? It may work...

Also long solution, it is possible to 3-cycle centres in one face, add a PLL-parity and a T-PLL.


3-cycle: r U (x') r U' l' U r' U' l U (x) U' r'
Shorter : Fw2 r2 U' l2 U r2 U' l2 U Fw2

Can anybody help me with finding 2 better algs for the ones i now have.

It's pretty easy, but is has to many setups of his own.
nr1: R2 F D2 (R’ U R) D2 (R’ U’ R ) F’ R2

Not to bad, but maybe there is a better one.
nr 2: F2 L2 (U R U’) L2 (U R’ U’) F2

thanks.

"nr1" is a classically bad case. I currently use L F' U2 F L' F' L U2 L' F

nr2: y'x' R U2 R D2 R' U2 R D2 R2

I like nr2, i'm gonna use that one. I thought the cube rotations would be a bad thing but it's an easy one. thanks.
I'm not very good on your nr1 version.
I made two variations on your nr1 version. i think i like the second one the most although it has a B2 move it flows pretty good. it's also possible to do a cube rotation within the first one to get the better trigger.

Is there any complete collection of algorithms how to flip any edge together with DF?

Right now I'm using only two algorithms, flipping adjecent and opposite edges in the U-layer; M'U'M'U'M'U'M'U2M'U'M'U'M'U'M' & R'U2R2UR'U'R'U2rURU'r .

What I want is to be able to flip any edge with the fastest algorithm or commutator. It might be setupmoves + one of these two, but if that's the fastest, then it's okey.

 

[Joël]

Hey guys... Just found another alg for flipping all edges in the E layer.. Maybe someone is interested:

(R U R' F L' U L) E2 (L' U' L F' R U' R') E2

It's commutator, and once you see how it works, quite intuitive.

I'll probably never use it, but I like it because the inverse of P is also it's mirror .

2 2 cycles of edges..

(R2 U' R' U')(R2 U' R' U')(R2 U R U)(R2 U R U)

 

[cmhardw]

Not sure why this edge 2 flipper is not listed. I used a google search on this forum to see if anyone else had posted it, and the only reference to it was Sarah using it in this post to solve three sides of the cube, but she added two turns to the end of it that changed the effect.

I "discovered" this alg on my own at one point, after I'm sure it had already been found many times over by others. I'm starting to like it more and more though.

I posted this thread a while ago after I found it myself. I agree with you though. It seems few people knew it and no one had really posted it anywhere:

I've known that for a while (I think it's on Erik Akkersdijk's old site?), it's very nice, but I use U' instead of U. PB is 1.43

 

[Sakarie]

I've used ACube and tried both optimal, <RU>-optimal and <RULMF>-optimal, and sometimes other things. What this is is the, according to me, speedoptimal algorithms for all the three-cycles that CAN be solved with only <RU>, but they aren't necessary only <RU>.

I use UF as buffer, so EVERY CYCLE is starting with UF. When it says "UR UB", it's actually "UF->UR->UB->UF". I might have cnaged the algorithm without changing the move-count, so it might not be perfect.

If you have an algorithm faster than "mine", please post it instead. But make sure that it may be faster, and not only that you practised it very much, and never tried "mine". Of course it's not my algorithms, but at least respect the work and time I've spent.

Yeah.. I knew that one, but occasionally I find algs that are new (to me, at least) and have something interesting to them (funny structure, commutator, repetitive sequences), and then I just want to share them with the world (or anyone that cares..). In this case I thought it was funny because there's a repetition, and the 2nd half is a mirrored (in the S layer) version of the 1st half.

Very cool alg! The only thing I don't like about it is how you have to change your grip to execute.

Sorry. I should have said its a weird grip to start. I meant it wouldn't transition nicely from executing most previous algs. (Unless you execute it differently than me?)

EDIT: I guess it doesn't matter as much for BLD... I was considering it for speedsolving as well.
