I found this J perm out the other day:

R U2 R' U' R U2 L' U R' U' L

Just wondering if any one has seen it before??

Wow, much better than my other one.

A-cube is one program that will generate algs for you.

I found the inverse (L' U R U' L U2 R' U R U2 R') myself.
It's a move-cancelling Niklas+Sune:
(L' U R U' L U [R']) ([R] U R' U R U2 R')

So yours is a Sune+Niklas...
It's fun to come up with these, though.

What does quarter-turn metrics, face-turn metrics, and slice-turn metrics
mean. I don't see how you would specify where the cubies would go on a
compleatly scrambled cube?

When I learned PLL, I learned that one for J. It's pretty fast. I think Gungz also uses this alg, since it's on his blog.

There's also its mirror:

R' U2 R U R' U2 L U' R U L'

that brought back memories of the corners first lags I used to use. I like the style of it but the one that I use can be done in one motion.

R U R' F' R U R' U' R' F R2 U' R' U'

The finger tricks are shone in this video I made of some PLLs.
it is the second one

I learned this alg to help out with my 2x2 solving, I then decided to see what it did on my 3x3 (how edges were affected) and lo behold, it's the J perm.

Wow, congrats pembo. very seldom do i find an alg that i replace an already faster alg with.... if that makes any sense, i've just learned two new algs today! yay!

That alg is pretty well-known, I've seen it many times... I use it for OH, but for regular speedsolving I usually prefer (R U R') (F' R U R') U' (R' F R2) U' (R' U')

The one I do is equivalent, although rotated and done from a different angle:

B2 L U L' B2 x' R B' R B R2'

That's how I write it, anyway. The way I actually execute it, the cube is tilted 45 degrees so that B2 feels kinda like U2.

I like the first alg better, I really hate rotating the cube during my solve, it always messes me up...

L' U R U' L U2 R' U R U2 R' is the best one in my opinion. 1.5 usually in a normal solve.

Ouch. You just made me aware my blindfold method description is even more outdated than I already thought. I've been using that alg for a long time and yes it's well known, though on my page there's another one which I didn't know until now. Anyway, here's a 1.20 video:

whoa, stefan, that cube is like unbelievably loose :shock:

how did you get it that loose without mad poppage?

(to stay on subject) if my cube was that loose, this new alg would be insanely fast!

That's the first combo I ever found. In 1981 I found that the two major corner algs, the main one that rotates three corners, and the main one that swaps two corners while rotating three of them, R U2 R' U' R U' R' and R U L' U R' U' L could overlap and combine.

I have since replaced it with R U' L U2 R' U R U2 R' L'

However I still sometimes use a variation of R U2 R' U' R U2 L' U R' U' L to swap two pair of edges and corners flip two edges over: Turn the whole cube QR' then do the alg as R2 U2 R' U' R U2 L' U R' U' r. (here lower case letters only move slices.)

I can flip those back over using only 9 moves now, but I don't know if I've already said too much.

Not really. Standard good speedcube I'd say. It's a deluxe, btw. Not sure why I used it for the video, maybe because it looks best on my poor webcam or it might've been my best cube at the time (it isn't anymore).

wow, that cube is easily 5 times better than the current cube i'm using... is this just due to it being broken in, or did you do some work on it to make it that loose?

hmm... the way i look at it, another 3 or 4 months with my DIY and it should be pretty fast :D

I also need to remember to re lube it.. i want to, but it's kindof cold outside, and i'm not allowed to do it inside...

the person using the cube is a huge factor as well dude :oops:

what what, you're saying i'm slow??

ha, jk man. :wink: I know i'm not that fast, but my cube definately isn't as loose as the one in that video. I need to re lube..... oh well, that is for a later day, it seems to be working out ok for me right now.

No trust me, I'm not even close to that fast. I'm just saying that a good cube will only help so much and the individual's skills are probably the main factor

yeah, i was sooooo close to beating my average today, i got it down to 26.54, then kept getting 29's and G perms...

hopefully all the snow will go away soon, then my cube shall be re lubed and i shall have something fast to work with! maybe then i can get Pembo's alg sub 2! It's already fast on my cube now, just wait until later!

i lossened each of the screws on my diy a half turn last night, still no pops during a solve. had one pop while working on some repetitive finger tricks. it helped more than i thoug it would.
