4x4 algorithm question

[Carson]

I am using the algorithms on the speedcubing.com site and am having some issues.

I am trying to use r2 U2 r2 U2 u2 r2 u2 to swap 2 LL edge pairs, but it just scrambles my cube. Am I just doing something wrong, or does this algorithm not work?

i dont think it does. you should use one of these:

pll parity:
(Rr)2 (Ff)2 U2 r2 U2 (Ff)2 (Rr)2
r2 U2 r2 (Uu)2 r2 u2
(Uu)2 (Rr)2 U2 r2 U2 (Rr)2 (Uu)2

Use the newer notation.

 

[nitrocan]

is (Uu) Uw? i really dont know the new notation

 

[rjohnson_8ball]

Correct, with 3x3 the symbol u has meant Uw, but with 4x4 and 5x5 u has meant the single slice near the U face and (Uu) meant Uw. (When it comes to bigger cubes I think people are still deciding proper notation.) I use
r2 U2 r2 (Uu)2 r2 u2 to swap 2 big edges on a 4x4 and 5x5.

 

[nitrocan]

how can you swap 2 edges on a 5x5?

 

[MistArts]

how can you swap 2 edges on a 5x5?

During edge pairing or just swapping 2 edges?

 

[nitrocan]

r2 U2 r2 Uw2 r2 u2 doesnt work on the 5x5, it messes up the centers.

Uw2 Rw2 F2 u2 F2 Rw2 Uw2

I am so confused... I can't even finish the 4x4 now because half of the information I find is in one notation and the rest is in another. I looked up the WCA official notation, but that doesn't help me since half of the stuff online doesn't use it. Can anyone point me to a guide or even a simple algorithm list that uses the new notation? Or can someone explain the "old" notation to me so that I can use the old guides?

Uhh, you can't switch edges on a 5x5. There is no PLL parity for 5x5. If you mean switch two wing edges, then you use 4x4 OLL parity.

watch the animation.

r2 U2 r2 U2 u2 r2 u2

r2 means twist the layer/slice that is inside the R-face
U2 is a normal U-face turn
u2 is = twist the slice that is under the U-face

All turns are half turns.

That must help

When switching too wings, it better to switch them on different tredges.
