Now I'm fully convinced the Cage Method for larger cubes is a very, very bad idea!

Has anyone ever discovered a generic alg for moving a center from any "row" and "column" to any row or column for large cubes? Some of these centers are just not listening to me when I derive what I thought would be the way to do it!

What do you do when you have a bar on 2x2 first layer? Usually I just take out one of the pieces that need to be swapped and replace it with the other one, then insert the remaining piece, but that takes way too many moves and prevents one looking. Anyone have an alg for this? I know when its Y-perm for first layer you can just do R2 F2 R2

R U' R2 F R2 U' R'

R U R' F' R U R U' R U R' U' (EG1 alg)

Edit: I don't do this though, usually I'll just use Ortega in such a scenario.

Another super similar F2L question...
Open slots in FR and BR, pairs that can be inserted with (R U R') and (R' U' R).
(U2) L R U' R' U L' U2 R' U' R
or (U2) L' R' U R U' L U2 R U R'

I guess this is the right place to ask.

Does someone have a list of feet PLLs? Do the top feet solvers even use special algs for that?
They do use special algorithms.
From Antoine Cantin's cubing website you can find some PLLs that he prefers to use for his feet rather than hands.
Here's Antoine's WCA record, just to give you an idea of his cubing experience:
I hope I helped.

Can I get a U-Perm alg with 'M' slices?

Hello, I learned f perm by R' U' F' t perm, and was wondering if there is something for v pern

here's something, but I wouldn't recommend it.

Laziest V-Perm ever: [R' U' R U', [R' U' F' : tperm]]
Wow, a 26-move V perm.

That's even worse than my 21-move N perm.

The cuboid algorithm for swapping the upper right front and back corners? (2x2 or 2x2x4) it is something like R2 U R2 U' then some other stuff

I use (R2 D' R2 D)2 R2 U (R2 D' R2 D)2 R2 to swap UFR and UFL?

Thanks that is what is way looking for!

Here's a shorter one:
R2 U' R2 U R2 y R2 U R2 U' R2 U
(domino T-perm)

edit:
If you need to preserve E edges do this instead:
R2 U' R2 U R2 y R2 U R2 u' R2 D
I'm doing this on a 3x3x3, so if you do it on a 2x2x4, instead of u' do a 3Uw'
