hello, i am here to request a humanly time efficient L4C alg set with purpose of speedsolving. i preferably want this in a pdf.

Can you point me to an existing document with all the cases, even if they are bad ones? I may try to work on this project
L4C is a subset of ZZLL (which is in turn a subset of ZBLL), and I'd expect that there are fairly optimised algs for the cases already and it's just a matter of copying them out of a ZZLL/ZBLL alg list.

You can find move-optimal algs on Birdflu: A B a b. (These four sets have some overlap because of symmetrical cases.)

For the case above but rotated y2 so the insertion happens in the back. Does anyone have any rotationless algs to solve it? The algs can have M slices, I'm just looking for something that's rotationless.

thanks
bump! Still looking for algs.

The best I was able to find by hand was M U' L U' l' U2 l U' l', but it's not very good. I tried CE too but the best it gave me was (U) R' U2 F' r B r' F U2 R. Wouldn't it be easier to just rotate? Rotations aren't always bad, after all!

E: That second alg might be better executed as x' R' F2 D' r U r' D F2 R x, but that's got two rotations :p

i found these algorithms
L U' L' U2 L U' L' U f' L f
L U' L' U2 L U' L' d L' U L
d L' U L U' L ' U' L
y' U L' U L U' L ' U' L

Thanks for the algs! I was hoping to find a smooth solution, but I agree, it's better to rotate :)

hey guys,

I have another request. Looking at the case below but rotated y2 so the insertion happens in the back.

I would like to be able to insert the pair in the back without rotating, so as before, I'm looking for some rotation-less algs.
Hopefully some ergonomic ones.
thanks

Not exactly the easiest to perform, but I do appreciate the suggestion. Have any other algs?

For these cases you keep posting, you need either L or B moves to get the edge into place if you dont want to rotate. Which would you prefer

EDIT: I think the optimal alg U r' U r B2 U' B isn't a bad choice. Left ring push for U, start by overgripping for the r'

thanks for replying. That alg is not bad. And I'm not concerned about L or B moves, just looking for something smooth to perform. Did you manage to generate others?

i'm requesting a speed optimal alg set. it solves the corners of the top layer (both orient and permute) along with the edge orientation of the top layer (ollcp), except the top and bottom layer edge pieces can change permutation and separation freely. it has 331 algs.

ex case (not optimal in the slightest)
scramble: M2 U S U2 S' F R U R' U' F' r' U2 R U R' U r solve: M' U2 M U2 M' U M' L' U' L U' R U' L' U R' U2 L

Here
ua) R U R' U R' U' R2 U' R' U R' U R
ub) y2 R' U' R U' R U R2 U R U' R U' R'
Is there any regripless versions. Is there a way to do those regripless or 1 regrip? Thanks

Edit:
For ab perm I just found F2,U,M',U2,M,U,F2, does anyone else use this? It sounds pretty good. You hold bar in the back.

That's a U perm, not an A perm. It's the optimal alg, so it's good to know for FMC (and feet), but for normal solving, the standard RU or MU algs are faster.

Try executing them a bunch of times, and try doing some of the U moves with your left index finger. This should eliminate regrips completely.

Do you actually expect someone to go and generate three hundred algs for a method nobody is going to use?
