Helicopter cube solving (and patterns)

[qqwref]

PS! Nearly every pattern is possible. Every center configuration is possible by jumbling. Only corner orientation is retricted!!

Yep, I said that already on post 2 ;-) But, even without jumbling, you can move full centers around in any way you choose. I used this trick when I swapped black and orange on mine to get the normal color scheme, because I wanted to move as few stickers as possible.

Ok. I will take it further. On a picture helicopter cube, exactly half the center permutations are possible (with jumbling). Corners will remain the same as normal helicopter cube.

PS! I mean "small" centers

Arrow pattern. I make this from 3 big flips. One flip each on FL, UB and RD edges respectively.

One big flip is made like so: UF UL FL (UF UL)*3 FL UL UF

Snake pattern. This is nothing but 2 easy 3-cycles on the centres.

FL BR (setup)
(UB LB LU LB)*2 (first cycle)
(FR FD FR RD)*2 (second cycle)
BR FL (undo setup)

Sorry no picture

Cool patterns. You should use a normal color scheme

Lazy to resticker Maybe I could use an applet??
Most patterns that move many pieces have too long algs ...

How do you swap 2 big centers? 2 8-turn algs??

Per

 

[qqwref]

Could you use an applet? You'd have to deal with not being able to jumble.

I don't know how to swap two center groups in two 8-move algs, I just know it can be done without jumbling. To be honest I don't care about optimizing patterns on this puzzle, just about quickly/efficiently solving.

There are many patterns without jumbling...

I don't care about speedsolving this thing Just like i don't really care about speedsolving any regular cube/puzzle anymore. I'm getting old i guess:rolleyes:

I posted a way to swap 2 face centers earlier. Ok here it goes:

1. UF UR UF FR UR UF UR FR
2. UB UR UB RB UR UB UR RB
It swaps U and R full centers.

Yet abother arrow pattern:

UR FL (FR UR)*3 (UF UL)*3 FL UR

Affects only U and F faces so it can be repeated on the other 4 faces ...

Do you mean:
UR FL (FR UF)3 (UF UL)3 FL UR?

Yes. Isn't (A B)*x and (A B)x the same??

PS! Hehe. I see my mistyping now!!

I finally sprayed my helicube with some silicon, out of some reason i didn't believe it would help but it became mush better. On one of my first tries after lubrication i got 1:00.96 witch is almost 15s better then my previous pb.

Good job, soon that will be average for you

Where do you learn how to solve one? I just got mine in the mail today. I've solved it up to the point where (if you hold it like a normal 3x3 cube) the front face's top two center pieces need to be swapped with the bottom center closer to you on the left or right (the front center on the left needs to be swapped with the left center nearest you, and same with the rights). In this diagram the letters depict center pieces and the top block is the F face.....................................................................................................................................................................................
..........................................................................................................................................................................................
......................B G...............................................................................................................................................................
......................R R...............................................................................................................................................................
................B B........G G
................B R........R G

There is two guides, my LL corners last guide: http://www.speedsolving.com/forum/showthread.php?t=21065
And Shambles LL centers last guide: http://www.shamblessoftware.co.uk/d_puzzles_helicopter_solution

PS: My PB with my corners last method is now 57.11

Sorry to bump old thread. I see no need to create a new one

2 quick patterns. Pictures will follow (added!).

Pattern 1:

(FL RD UB UL FD RB)*2

Pattern 2:

(FL RD UB UL FD RB)*3 (this can also be done like this: (UB UL)*3 (FL FD)*3 (RD RB)*3)

Per

Yet another pattern. Strikingly short, IMHO.

I was playing around with some trivial moves, UF UR FR. Then i simply repeated these turns 4 times. This gave the pattern with only a few missing centres. These centres were fixed with a 8 turn alg. This gave 6 cancelled turns!!:tu

Full sequence: (UF UR FR)*3 UR FR UR UF UR.

Per

PS! I also found a 16-turn sequence and a 18-turn sequence for this pattern. The 18 mover goes like so:
((UF UR FR)(UR FR UF)(FR UF UR))*2

And the 16 mover has 3 parts
1 (UF UR)*3
2 (UR FR)*3
3 FR UF FR UR UF FR UF UR

This shortens to (UF UR)*2 UF FR UR FR UR UF FR UR UF FR UF UR

Oh well, noone seems interested...

PPS! Using the last five turns of the first sequence, i found out i can simply repeat them 4 times over.
(UR FR UR UF UR)*4. This yields another 14-turn sequence...

Using (UF UR FR)(UR FR UF)(FR UF UR) from the 2nd seqence, i can insert UR UF FR (UR UF)*3 FR UF UR and then do a FR turn at the end. Another 14- turner. Ok, enough is enough!!

BTW guys, I just got it and have no energy to read the whole tread, I got a situation where I can solve all but two swapped centres, did that happen to you too?

Yes!
But i have a alg that swaps two centers only. UR UL jumble front left or right corner UF UR UL.

This thread is also about patterns but i haven't seen any :rolleyes:
I found a nice star and did it on two sides of the cube. It takes no jumbel moves to do it.

The other side.

Finally i have a good sequence for this nice pattern.

(FL FD RD RB UB UL)*2 (UB UL)*2

A semi-random find:tu

Sod that. I already improved it to (FL FD RD RB UB)*2. Now beat that

Per

 

[mrCage]

Slight variety of the previous pattern. It consists of 4 short conjugates. The first 2 cycles 3 blocks. The last 2 cycles 3 other blocks. Both duplets twist the same 2 "center-edges' effectively cancelling the side effect.

UB UL UB . FL FD FL . RD FD RD . FL UL FL

Picture follows shortly!! (added)

Per

PS! I posted this pattern a few posts above, but a different sequence. Hmm... Pattern blindness!!
