Hi there, have been trying to resolve this for the past week. I kept ending up with 2 unsolve corners on the last layer of the 4x4x4, i will basically need to swap these 2 corners before i can oriente them. Has anybody seen this type of issue before?
Why are you using obsolete notation?You have just got PLL parity, do 2R2 R2 U2 2R2 R2 2U2 2R2 R2 2U2 and you will either have an F perm or a T perm depending where you did it
I like the other version of that algorithm with the slice moves more.You have just got PLL parity, do 2R2 R2 U2 2R2 R2 2U2 2R2 R2 2U2 and you will either have an F perm or a T perm depending where you did it
no I meant using direct slice moves like M2 and not do wide R2 and R2 which is a equivalent of M2,That one is the slice one.
The notation you're using may be popular (e.g. CubeSkills uses that too) but it's bad notation and this is the hill I'll die on.Geez, how many notations are there for 4x4? I write my PP alg like this:
r2 U2 r2 Uw2 r2 Uw2
With x being a slice, Xw being a wide move, and X/X'/X2 being outer layer turns
Why does this notation is worse though?The notation you're using may be popular (e.g. CubeSkills uses that too) but it's bad notation and this is the hill I'll die on.
I've done a fair number of big cube reconstructions (some have not been added to cubesolv.es yet) and it would have been hell if I had to write all of those in modified Singmaster(?) notation. You may have noticed that all of Brest's, Stewy's and my big cube recons use SiGN notation. There is a reason for this! SiGN is just better.
It's honestly kind of embarrassing that as a community, we've been so terrible at standardising big cube notation. WCA notation is universally understood, but cannot represent slices. Singmaster-based notations are awful but popular because that's what many older tutorials are written with. SiGN somehow never managed to catch on, except among people who actually have to deal with big cube notation frequently. Our weekly comp uses ancient WCA notation (wtf!) for 666 and 777 scrambles.
I'm assuming you're referring to Singmaster-based notation (with lowercase letters for inner slices).Why does this notation is worse though?
Doing parity from certain angles can give you a better PLL. You are doing the right alg for adj parity which is just sexy parity reverse sexy. Just try and figure out how to get the best PLL. Watch this video by SCRAre there algorithms for the different PLL parity situations?
For opposite/diagonal corners,I usually do the opposite edges parity then a v-perm. For adjacent edges in the UF and UR spot, I will usually do a R U R' U' then the opposite edges parity, then U R U' R'.
Are there better algorithms for this? I find myself taking what feels like way too long for these cases
The basic:Are there algorithms for the different PLL parity situations?
