New (?) 4X4 Method Ideas

[cardsNcubes]

Hey guys, I don't know if these have been thought up before, but here are a couple of ideas I had for solving a 4X4.

F3L - Basically Friedrich F2L with an extra edge
1. Centers
2. Cross
3. Create/Insert Corner-Edge-Edge "pairs" or sets
4. Last Layer (OLL + PLL)

Also (my favorite)

CFX4
1. Make 1 full center & bottom half of all other centers. except opposite side (white=full center, yellow=no center yet)
2. F2L
3. Expand off upper corners, create 2x2 blocks
4. Solve like a 2x2

I don't have my Eastsheen 4x4 yet, so I don't know if these are even possible. Any feedback is appreciated.

These methods are possible, but useless for speedcubing

CFX4 makes no sense. If you make 1 full center and expand that to 2x2 blocks from the corners later..... well, try it after you get your Eastsheen

I hope you will try to solve your 4x4x4 without any help from the internet.
But afterwards, look up reduction if you want to get fast

does solving it by myself to the point of parity count? just curious lol

I'll try to solve it by myself, because i didn't with my 3X3. I actually meant expand off the upper corners. Sorry I didn't clarify. I'll try it, because when I say it it sounds impossible, but in my head, I can see it working.:confused:

Either way, thanks for the feedback

I posted my revenge method in another 4 by 4 thread... But I feel that it especially relevant to this thread. I happened to make a method called F3L a few days ago:

http://web.mac.com/teisenmann/revenge/F3L.html

WHAT A COINCIDENCE :U

From my experience, it's less efficient to solve the cross first, because it gives you less room to make corner-edge...-edge sets. It would be interesting, however, to generate a set of revenge OLLs and PLLs. There would be a lot to memorize (you'd probably do a multiple step OLL and PLL). I prefer commutators, personally. ;P

It is definitely possible to solve w/o a solution from the web... My method uses only one memorized MOVE SEQUENCE to solve for edge parities... And I generated the move sequence from an arbitrary set of repeated moves (r' U2 r' U2 r' U2 r' U2 r') and I stuck a commutator at the end to neaten up the result.

I solve edges differently than most people, here are a few pairs.

blue on U and orange on F

scramble - u' f2 R L' U2 B' l r' U b2 r b l2 L' D' F R l' U' l' B2 f R' d2 f2 b2 d L2 l2 D' f' L' d2 b2 R' r' b D2 B' F2




centers

blue - R' d2 f'
yellow - U r' F r
green - R' d B d' B U' l U2 l'
white - u' B L2 u L u' L2 u
red - z'r2 U r2 D' r2 U2

leave the bars scrambled







pair 1 - U R U' r
pair 2 - B' R B r'
pair 3 - F R2 F' r'
pair 4 - F' L F l2
pair 5 - R' F R F' r2
pair 6 - F' L F r'
pair 7 - U L' U' l2
pair 8 - F' L F r2



Anyone else use this? I just found it one day while messing around. Pretty ballin'.

hmm. I can't get that scramble to work :/

Do you mind actually saying what you do instead of giving an example?

Try this (even if he's missing a pairing).

 

[Kyle™]

Thanks Lucas, and yeah I left out the last pair because I am sure everyone here knows how to do the rest, plus 3x3x3 stage. With this method, you can avoid really crappy diagonally swapped pairs often. I like it!

woah thanks Lucas!

Hi, My name is Hong Chen and I created F3L and F4L method solveing 4x4x4 and 5x5x5 for more than 5 years. My first attempt was on 2005 Sweden open. I created this method one week after I got the cube and at that time I had not known any other methods.

This was first mentioned by Chris after 2007 Canadian open in the thread
http://www.twistypuzzles.com/forum/viewtopic.php?f=8&t=7208&view=previous
He broke the WR of 3x3x3 BLD in that competition.

It can be used as speedcubing and my best time in competition is 70 seconds in 2007. I am old time cuber (46 years old) and do not have fast hand. But I think people can solve this under 1 minute with fast hand and that is not bad. The most fun is in the searching the algorithms and I think because I am not using reduction I know a lot more algorithms in last layer than most of the people. I created youtube at

The total example in Java was at

And here is the result of WCA competition.

All the 4x4x4 and 5x5x5 are using F3L and F4L.
