Half-Parity Issue

I am composing an algorithm for the 4x4 cube, and along the way, I have come across an interesting form of parity. I guess you could call it Half-Parity? If anyone has any idea how to fix this, I would really appreciate it.

Give me a moment...

Does this work?

r' D r U r' D' r U r' D r U2 r' D' r

OK... When I got to that point, as I said before, I am developing my own algorithm, and I passed one of the steps with a interesting method, and I must have done your algorithm wrong, because it screwed up everything, and now I have to remember how to do that step before I can check again.

can anyone generate algs for OLL 39?

i don't mind lefty algorithms, but it's hard for me to do L F' L' U' L U F U' L' cause I can't do F with my left thumb

if its RUF, r R U F or any of that I'd be very grateful

feliks alg is a bit difficult aswell r U' r' U' r f R f' r'

Here are some: (just took some of my OLLCPs)
r U R U' r' F U R' U' F'
R U R' F' U' F U R U2 R'
R U2 R' U' R U R' F2 r U r' F

R U2 R' U' R U R' F2 r U r' F

bless you that third one is wonderful

 

[guysensei1]

I have to say no on this, maybe this CPP will do? It "only" does op in the D layer: / (3,3) / (1,0) / (-2,4) / (2,-4) / (5,0) / (-3,-3) /

, or you can have a look at my Sq-1 PLL page, but there is nothing shorter than 10 twists.

What do JN and JJ mean?

 

[Cale S]

What do JN and JJ mean?

J = J perm = adjacent swap
N = N perm = diag swap

 

[guysensei1]

J = J perm = adjacent swap
N = N perm = diag swap

Some of those algs seem terribly long them, with 2 or 3 J perms in there...

 

[Lid]

Just look at the CP page

JJ=Jperm in both layers, JN=Jperm in U+Nperm in D.

soln: R' U2 R U R' U' R / setup: R' U R U' R' U2 R
soln: R U2 R' U' R U R' / setup: R U' R' U R U2 R'
Can anyone provide algs for these F2L cases that orient two or all edges when none are?

 

[TDM]

soln: R' U2 R U R' U' R / setup: R' U R U' R' U2 R
soln: R U2 R' U' R U R' / setup: R U' R' U R U2 R'
Can anyone provide algs for these F2L cases that orient two or all edges when none are?

To orient two edges:
R' U2 R U' r' U r U r' U' r
R U2 R' U r U' r' U' r U r'

Just using an easy VHLS alg instead of the regular insertion.

[unsolved]

I forget how to do this on the 5x5x5. Wings edges on the front/back flipped.

 

[Christopher Mowla]

Here's an optimal alg (there are several such algs which were found by many at least a decade ago). 12 moves.
2L' U2 2L2 F2 2R' D2 2R' D2 2R2 F2 2L' U2

 

[unsolved]

Thanks! So far my program has found 24 solutions. I imagine more will appear once the starting move D2 is tried.

Edit: Nope! Only 24 solutions according to my move generator.

 

[turtwig]

Skewb U perm at a y2?

 

[DeeDubb]

I'm looking for an alg that twists ULB and DBR, one clockwise, and one counterclockwise, and vice versa (without affecting the rest of the cube of course). I'm trying to find a slightly upgraded corner twist fix method (compared to OP)

EDIT:
