Help with BLD corner Commutators

[McWizzle94]

Hey everyone, I'm trying to learn corner commutators for BLD. So far, I know how to do most 3-cycles. The things I'm having trouble with are having to do pairs of 2 cycles and misoriented corners at the end. Could somebody please help me with this? Thanks

i saw that already but it didn't explain everything that i needed

There's plenty of literature out there:

If you understand commutators in general, and maybe see some examples for other piece types, then corners should make more sense.

Hope this helps,

I usually just break into new cycle when l have 2 2-cycles.

Chris, thanks for the link, 4x4 center commutators are fun
I'm still a beginner but what ever.
Hopefully by Virginia I can do the 4x4 BLD

Oh yeah? Why the sudden interest in 4x4 BLD? Who taught you those commutators?

i had an interest in 4x4 BLD, but it didn't work too well xD. you can probably do a lot better.

anyway, thank you all for your help, but could anyone give a few examples solving the corners with commutators please? you don't need to add in edges though. thanks

Scramble: B' F2 R B2 F2 R' F D' B L2 R B' F' U' L2 R2 B' R2 U2 F' D F B2 U L2

I start from UFL, so the corners are: UFL->FLD->FRD->LBU->UFR->BUR->DRB->DLB

UFL->FLD->FRD: U' R U L' U' R' U L

UFL->LBU->UFR: y' R'2 D R' U2 R D' R' U2 R' y (set up with y' R2, cancellation in the end)

UFL->BUR->DRB: x' U L' U' R' U L U' R x

Then there's parity left.



Another scramble: D B2 L2 U' F' U R2 U' R D L2 D' U B2 F' D B2 F R2 L2 U F2 R' L F

UFL->UBL(break into new cycle)->URB->DLF->BLD->FUR->FRD->BRD->BUR

UFL->UBL->URB: (A-perm: x L2 D2 L' U' L D2 L' U L' x')

UFL->DLF->BLD: you can do D to make it an A-perm on the F-face, which is IMO the fastest solution for this case. But this is a shorter solution: D' L2 D' R' D L2 D' R D2 (D' is set up, and there is a cancellation in the end)

UFL->FUR->FRD: Again you can set it into A-perm (with R). Shorter solution: R' F2 R' B' R F2 R' B R2 (set up with R, cancellation in the end)

UFL->BRD->BUR: x' R D2 R' U' R D2 R' U x, or again you could set up into A-perm, with R'.

I hope this helps.
