L2L4 - The Lost Methode ? Help Find it!

[oll+phase+sync]

He I read on Chris Hardwicks Webpage about an "upcoming" mehtode called L2L4
With lower movecount then Fridrich and an reasonable amout of algorithems (more than Fridrichs)

But I couln't find any further info on this methode, not even a concept.

If You have some kowlege about it, plese share it.

I actually emailed Duncan about this method a while ago and he said he'd send all the resources. Never did though.

Not like I need them.

F2 R L U' B2 F' D B F L2 D F' U F2 U D L' B2 L2 U R U' D' R2 U2

1) U B' L F L F' L2 F2 L' F R U' x2
2) R' D2 L2 D F D R2 U2 R'
3) R2 B R' U B U2 R2 U R B' U y
4) R2 U2 F R F' U' R2 F' U' F U' R2 U2
5) R' U R U R' U2 R U' R' U' R U2

I do CO/CP/EO/EP, but I'm unsure of which order would be best. I think it's about 90 algs.

Am I stupid or isn't just step 2+3=CLL?

Am I stupid or isn't just step 2+3=CLL?

No. CLL Would imply that first layer corners would already be permuted.

 

[irontwig]

No. CLL Would imply that first layer corners would already be permuted.

...which they are in the example.

 

[RyanO]

I didn't look at the example, but CP/EO still isn't the same as CLL.

 

[Kirjava]

no, it's not CLL

 

[irontwig]

I didn't look at the example, but CP/EO still isn't the same as CLL.

Then look at the example ***.

no, it's not CLL

Who are you talking to?

I do CO/CP/EO/EP, but I'm unsure of which order would be best. I think it's about 90 algs.

As far as I get it:
1) Build FirstLayer - Was the Center Alignment intendet? I dont See an Reason for it?
2) and 3) I would do U FR'F'R U2RU2R' y to CO/ CP for the last Layer -> 42 Algorithems similar to Roux - Middle Layer Edges are oriented - intention or luck ?
4) M'UM'UM'U2 MUMUM - this one was easy but this sounds like alot of algs ... only 18algs I believe
5) 8 edges 8!/2 (~6500) possibilities I think this is only possible in at least 2 substeps

Did I miss somthing important?
What does L2L4 mean by the way?

EDIT: WARNING I mixed in CLL wich is not present in L2L4, You may just read on.

Anyone up for an alg-genning session?

(Is there a better [short] verb than 'genning' for this?)

What does L2L4 mena by the way?

1) First layer.
2) Corner orientation + solve a middle edge (FL)
3) Corner permutation + solve a middle edge (FR)
4) Edge orientation + solve a middle edge (FR)
5) Edge permutation + solve a middle edge (BR)

Now I got it, that's cool, just by changing the Order of Step 2) through 5) one would get a new variation of this Methode.
Sadly each variation need also an alg variation.

What's about a Quiz - Which Step Sequences are bad?

 

[JeffDelucia]

I think that CO CP EO EP is best as far as recog goes. So for alg "genning" that is probably what you should start with.

 

[Joker]

90 algs? Reasonable.
Ill try out the scramble and solve later
EDIT
the solve doesn't work
EDIT
Nvm, I didn't think x2 mean the rotation, I thought it meant the alg twice as in *2
Now my thoughts.
Seems like it could be pretty fast. Make F2L shape pairs, and put 4 of them in one layer so they connect with a center, to solve a layer, or do LBL.
Then the rest...you need to get fast at recog and execution.
Get that down, and it has potential.

What's wrong with "generating"? Or didn't i get your verb?

 

[Joker]

Generating is too long.

Well, one consideration is that you pretty much have to do EP last because permuting 6+ edges in one step is too many algs. It's also easier to do EO after both corner steps because then you have fewer edges to orient (= fewer algs). And it's always better to orient corners before you permute them for recognition's sake (# of algs doesn't change if you swap the two corner steps). So CO/CP/EO/EP is pretty much the best sequence.

As far as alg making, good luck.


What about a backwards L2L4 where you first put together the cross and the rest of the SECOND layer, then put in the first layer corners while solving one part of the LL in each step? Is this at all feasable?

STEP2: - Corner Orientation plus solving on Middel Layer EDGE:

Does it matter wich Edge I solve?

doublesune OLL -Case (Headlights Front and Back):

R2 U2 R U2 R2 moves an Edge from UR to BR (E adjustment will make the edge orineted)

But Iwill need more algs if there is no matching Edge in U Layer.

Like R2 D2 L' U2 L2 it will exchange two oriented edges FR <-> BR

...

Is this kind of alg generation correct?

x2 really mean rotation - the example solve works I tried multiple times. Regarding "put 4 of them in one layer" - Is this a new Methode or L"L4?

EDIT: sorry for this late night Error of mine: this stuff I wrote about 5 edges. I again agree that orienting 7 edges is really much more algs than 6edges.

In fact with most of your thoughts about step sequence I agree, but: EO with 6 instead of 5 Edges ist just 3 algs more, CP on the other hand is an very easy step, but doing it with Oriented edges may opens the door for aditional shortcuts with simple recog.
