Learning the 4x4

[veazer]

Alright, so I bought my first 4x4 since I am already goodish at my 3x3, and I will soon be without internet access for 2+ weeks.

With that in mind, where can I find a good list of all the algorithms for the oll/pll parities on a 4x4, and the algorithm for flipping one of the dredges over? (when pairing them and they are directly across from each other as the last 2, you flip one, right?)

And is there anything else I should need to know?

P.S. I can already solve the 4x4 slowly using reduction, but I have to go look up algorithms for each wierd LL case I run in to and haven't found a good list.

so i should learn this to swap U & F centers: r U2' r2' F2 r
and This for swapping L & R centers: u2 R2 L2 u2

Then for flipping the FR dredge to solve the last 2 dredges: (R U R' F R' F' R)

BUT... what do i need to know for the last layer?

one OLL of these 3:
l2 B2 l U2 l U2 (x') U2 l U2 l' U2 l U2 l2 U2 (flips UF dedge)
r2 B2 r' U2 r' U2 (x') U2 r' U2 r U2 r' U2 r2 U2 (flips UF dedge)
r2 B2 U2 l U2 r' U2 r U2 F2 r F2 l' B2 r2 (flips UF dedge)

and One PLL of these 2:
d2 r2 U2 r2' R2 U2 r2 d2 (swaps UF with UB)
r2 R2' U2 r2 R2' u2 r2 R2' u2 (swaps UF with UB)

Or should I just learn these two (long and annoying ones) for the LL:
r2 B2 U2 l U2 r' U2 r U2 F2 r F2 l' B2 r2 Fixes Orientation parity but doesn't change the parity of the PLL
(l2 B2 l U2 l U2 (x') U2 l U2 l' U2 l U2 l2 U2 (x)) Fixes Orientation parity and also changes the PLL parity.

So basically what I am asking is this, should i learn this algorithm?

(l2 B2 l U2 l U2 (x') U2 l U2 l' U2 l U2 l2 U2 (x))

Yes, that is parity, you need it for redux on 4x4.

 

[veazer]

but that is to fix both parities at once, therefore, should i learn it or just learn to fix each parity individually?

 

[jcuber]

Just use the one that fixes both to fix OLL, and then the standard PLL parity alg. I use the standard double parity alg to fix oll, but it looks like you would use a different one. It doesn't really matter.
