Cube Challenge: Invent your Own PLLs

byu · Apr 28, 2009

Not sure if this is the right place to put this...

After I invented an R-Perm by combining two OLLs a few days ago, I've been inspired to try and create a set of 21 PLLs with no help at all. If you're interested, you can try on your own too. I'm putting my algorithms in white, so if you want to try, you don't see mine.

Ra (18):
R U2 R2 F R F' R U2 R' U F R' F' R U R U' R'

Also, to make the challenge harder, try and make them as few moves as possible, yet still coming up with them yourself (no computer alg generator)

Here's a very inefficient CW A perm:
L U' R' U L' U' L U' R U L' U' R' U2 L U' R U L'

I mirrored an RUL V perm and combined it with an RUL Ja perm.

I'll try to find a CCW A later.

I invented (?) my own Jb perm. It is the 2x2 alg from another angle.

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

I use that alg but backwards...

i intuitively got some,

H perm: (M2 U) x5 M2 U'
another: T perm twice (with lower case R moves) => (r U r' U' r' F r2 U' r' U' r U r' F') x 2

A perm: T perm once (lower case r moves) U => r U r' U' r' F r2 U' r' U' r U r' F' U

=)

L2 U' Lw' U L' Fw2 L U' L' Fw2 L2 U' M U L2
That's a F-perm on the D layer

Totally intuitive J perm:
(r' D' r) U (r' D r) U (r' D' r) U2 (r' D r) U (16f)
Intuitive N perm:
(L U' R d2 R' U L') (R U' L d2 L' U R') (14f)
Similar E perm:
(L U' R D2 R' U L') (R U' L D2 L' U R') (14f)
Similar intuitive H perm:
(L R D2 R' L') U (L R D2 R' L') U (12f)

Edit: Here's a weird intuitive J perm:
R2 U' (R2 l U l' U' R2 U l U' l') U R2 U' (13f)
Edit 2: Oh yeah, almost forgot, silly intuitive Z perm:
(L U' R E2 R' U L') (R U' L E2 L' U R') (14f)
And here's an unconventional intuitive U perm:
F' (R' E R U R' E' R U') F (10f)
A similarly unconventional A perm:
F' (U R' D R U R' D' R U2) F (11f)

Edit 3: Unknown.soul's A perm turns into a (non-intuitive) V perm if you sort of force an OLL skip near the end:
L U' R' U L' U' L U' R U L' U2 R' U2 R (15f)

Do you mean:

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

You can do the same with 10 moves only:
(L R U2 R' L') y (L' R' U2 R L)

i made also a new H perm: S R' U2 R2 U2 R2 U2 R' S'

first alg using S

PLLs: 8/21

U Perms
1. M' U2 M U M' U2 M U M' U2 M
2. M' U2 M U' M' U2 M U' M' U2 M

H Perm
3. M2 U M2 U M2 U M2 U M2 U M2 U'

G Perms

4. (R U R' U')x3 U y (R' U R U')x3 (R' U' R U' R' U2 R) U'
It's actually quite fast. Two quick triggers and an anti-sune.

5. U (R' U2 R U R' U R) (U R' U' R)x3 y' U' (U R U' R')x3

6. (L' U' L U)x3 U y' (L U' L' U)x3 (L U L' U L U2 L') U

7. U' (L U2 L' U' L U' L') (U' L U L')x3 y U' (U' L' U L)x3

Z Perm
8. R U R' U R U' R' U R U2 R' U R U R' U R U' R' U R U2 R' U'

lol i put the same one up

JBCM627 · May 1, 2009

Yay pairswapping algs! I actually use the G's, N's, E, and spoiler tag here too:

Ga:
z x2 U D R2 U' D' x' U' R D' R2 U R' D
Gb:
z x U' R D' R2 U R' D x' U D R2 U' D'
Gc:
z U' D' R2 U D x U R' D R2 U' R D'
Gd:
z x U R' D R2 U' R D' x' U' D' R2 U D

Na:
z (U R' D R2 U' R D')*2
Nb:
z (U' R D' R2 U R' D)*2

E:
z (U R' D Rw2 U' R D')*2

Don't use these:
Ja:
y2 z U' R D' R2 U R' D R' U' R D' R2 U R' D
Jb:
z U R' D R2 U' R D' R U R' D R2 U' R D'

And the H posted by TMOY which I use for OH:
R L U2 R' L' y R' L' U2 R L

The spoiler tag: [spoiler][/spoiler]
Which makes it nice for people like me who use the standard blue theme and quoting, because I can see the white text.

Here's a 'useless' H:

B2 R2 D2 (F2 L2)*3 D2 R2 B2

You can also make a useless Z:
R2 U2 F2 U (F2 R2)3 U' F2 U2 R2 (14f)

rachmaninovian · May 1, 2009

on a 4x4: r U r U r U r U r U r U r U r U r U r U' -->H perm xD

d4m4s74 · May 1, 2009

Here's a Z perm I've made up and used for a very long time because I was too lazy to learn one (now I've got a better one without F moves)
M2 U' F2 M2 F2 M2 U M2 (12f)

soccerking813 · May 1, 2009

Here is am H perm I made intuitively: F B' U R2 U2 R2 U2 R2 U B F'

And U perms:
CCW: R U R' U' L' U' L U2 R U' R' U' L' U L
CW: L' U' L U R U R' U2 L' U L U R U R'

Haste_cube · May 1, 2009

intuitive J(mirror) perm with 11 moves: L U' R' U L U2 R U' R' U2 R

Stefan · May 1, 2009

J perm: L' [R' d2 R, U] L
