40-ish that are exactly 10htm and about as many that are 9 or less ircc, now when you mention it maybe I should finish learning them, at least before Enschede if I can come.

Linky please? If I go to Enschede (which I probably will if I have enough time off work), then I would actually have to think about learning stuff for FMC

 

[guusrs]

And he mentioned during the Twente Open that's he learning the 11 move cases too!

No no, I'm learning some 11-move algs, not all!
Special cases like R' B L2 F L' . F . L F' L2 B' R (U2) (-;

And I cannot perform all 10-move algs for linear solves, I recognize them as an 10-move alg and often I need and extra cube to figure out which side to start, and for mirror and inverse cases.

From a computer generated list I got from Teemu, so some of them can be a little odd execution wise (like the 6 mover).

No, no; don't be so modest

Thanks for sharing!

See also his post with 10-move alg and up to 9-move.

And some tips:

While I was investigating these LLs up to 9-move, I noticed you don't have to memorise all algos, like 3-cycles and common OLL/PLLs. If you skip them, it becomes relatively easy to memorise all 6- to 9-move LLs.

Less well-known:

R U R' U' R' F R F' is a pair 3-cycle.
Lw F R' F' Lw' F R F'.

R B' R B2 L' B L B2 R2 is a pair 3-cycle with R conjugate (Fat A-perm).
R (B' R Fw2 R' B R Fw2 R') R'. So you don't have to memorise it.

R U' B L U L' B2 R B R2 is also needless to memorise.
R (U' L Dw2 L' U L Dw2 L') R', or
R2 (Fw2 D B2 D' Fw2 D B2 D') R2. You can construct it.

 

[irontwig]

Yeah, one should really look for pair-cycles too and two alg combinations for that matter.

 

[Cubenovice]

THX guys, I thought I had seen LL algs in this thread before and it seems I was right.
At the time I was not interested in algs but times have changed

 

[nickvu2]

noobish question: Do you all have a general strategy for transitioning from F2L-1 to L3C? Right now I'm doing EO + Phasing and just hoping I get solved edges and a corner, which obviously only works out occasionally.

 

[irontwig]

My general strategy is building pairs and trying to EO at the same time or finish (pseudo) F2L.

Scramble: U2 L2 B2 L2 F' R2 U2 B F2 R2 U2 R' B R' F2 L' F R D F2

Turn pre-scramble R2 for better understanding.

Orient edges: F2 D
EOLine + square: F' L' R B'
Expand block: L2 F
F2L minus 1 slot: D2 L D2 R
All but 3 edges: F L F' L' F'
Correct pseudoness: R2
Edge 3-cycle: F' E' F2 E F'
(25 HTM)

Nice as a linear solution, but I think there's better continuation after EOLine + square. Anyone?

 

[mycube]

if someone is interested in first sub*whatever*:
my first sub30

scramble: B2 D R2 F2 D L2 B2 F2 U2 B2 U F L2 D L R B U´ L2 F´ U
premove U´
B L D2 F´ D2 – 2x2x2 [5+1/6]
U B – 2x1x3 [2/8]
U´ F´ U´ F – another 1x2x2 [4/12]
B´ R B – EO [3/15]

Solution to L5C:
B L D2 F´ (2) D2 U B (1) U´ F´ U´ F B´ R B U´

(1) = F D´ F´ U´ F D F´ U (8-3/20)
(2) = F D´ B´ D F´ D´ B D (8-4/24)

Solution:

I found this 23-move solution:
Your start:
Orient edges: F2 D
EOLine + square: F' L' R B'
Expand block: L2 F
switch to inverse scramble,
B R2 L2 F’ more 2 edges,
L’ R2 B’ L B’ leave 4 oriented edges,
L’ F2 R L’ U2 D2.

 

[guusrs]

I found this 23-move solution:
Your start:
Orient edges: F2 D
EOLine + square: F' L' R B'
Expand block: L2 F
switch to inverse scramble,
B R2 L2 F’ more 2 edges,
L’ R2 B’ L B’ leave 4 oriented edges,
L’ F2 R L’ U2 D2.

Wow Atilla awesome,
I puzzled on this scramble & start too, but couldn't find better than 25 moves.

Hmm, great, I couldn't figure out how you found the first 9 moves though...

Now I have a time, and find the following 23-move solution.

Scramble: U2 L2 B2 L2 F' R2 U2 B F2 R2 U2 R' B R' F2 L' F R D F2

Pre-scramble: R2

Orient edges: F2 D
EOLine + square: F' L' R B'
Expand block: L2 F
F2L minus 1 slot: D2 L D2 R (the same start)
All: R' F' R F2 L F' L' F' R' F R F'
Correction: R2

 

[Attila]

Hmm, great, I couldn't figure out how you found the first 9 moves though...

After the switch i tryed to solve the corners, my first attempt was: L B’ L B’( a simply Guimond alg.), then before it to insert „B M2 B’ ” moves (which does not change the corners position). Finally more an plus move solve the 8th edge.

 

[okayama]

Quite lucky scramble from Japanese forum

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

All but 3 edges: L D' B' D' B2 D L' D' L2 F L' F' D' (Found with premoves F L' F' D')
Edge 3-cycle: D2 R2 Dw2 B Dw2 R2 D2 B

resulted in 20 moves.

The mess is because I was working on a pseudo-F2L. I figured out the premove, and went to solve the cube so I could rescramble with it. But then I got the PLL skip while solving

FM cubers,

I've not been following this forum for some weeks. But I want to spice it up with the puzzler I came up with years ago.
Generate the following state:
L2 D' R B2 R' D L U2 L
Now, orient the cubies in less than 8 moves and finish with a last layer permutation!

I will post the solution and one new puzzler like this a week from now.

Hmm? I cannot understand what to do exactly...
I know the LL alg, but should I solve it in another way?
