Roux Misoriented Centers Table

For years, on the official Roux site, there has been a short list of EO + LR cases that take advantage of misorienting the centers. I have completed a table for all of the cases. While it's always great for FM, of course you wouldn't memorize all of these for speedsolves. Many are easy to recognize and can take off as many as 4+ moves compared to the path you would normally take. Those are the ones you should learn. Not all will purposefully change the center orientation. The goal is to orient the edges and solve UL+UR in as few moves as possible. Sometimes it's possible to solve a case in fewer moves when R, r, or F are added, but for now I kept the table MU based. After performing each one the edges will be left in a three misoriented on U state or, in a few cases, all edges oriented. I have placed letter codes beneath each sequence to show the total move count not including the initial AUF. The G means the guaranteed length and P is for the potential length. This is because UL+UR will be slotted either with the final move or will require a placement on D then U2M2. The top row shows the edge orientation and the left column shows the UL+UR location.

I found these by hand and spent a lot of time on each, but I think some can still be improved. I plan to run all of these through a solver and may add it to the wiki sometime soon. If you find a mistake or something better for a case, post to let me know.

Great Work! You found 285 cases by hand. I am going to look through this although I always finish F2B with the centers correct or opposite (helps my recognition).

Example solve please. I dont understand. :(
Scramble: M' U M2 U2 M2 U M2 U M U' M U M2 U2 M U2 M U2 M2 U2 M' U' M U' M'
2 Misoriented:
AUF: U2
Alg from table: UM2UM'
Now all edges are oriented, continue with 4b

Scramble: U' M2 U2 M U' M U2 M U M' U' M' U M2 U2 M' U M U' M U2 M' U' M' U2
4 Misoriented:
AUF: U
Alg from table: M'
Now 3 edges on top are misoriented, continue with:
U M' U M'

Close, but notice the orientation relative to the corners. The solution would instead be:

AUF: U
Alg: UM2UM' (notice this puts the LR edges in a better position than your solution)
Finish: UM'U2M UM2U2M

better alg for one of the cases RUr'MUM'U'rU'R' and inverse
i know more will post later maybe

thumbs up for putting the effort into that

Thanks. I added it to the table but it didn't look right. When I edit this into the wiki, I should be able to make this easier to understand and include both RrMU and MU. Also, the inverse has a 7 move MU solution.

Yeah you're right about the inverse whoops
Also RU'r'U'M'UrUR' and inverse
R'FRU:M2 is same as optimal
Theres obviously M':B'RB or the A9 for the ELL etc

These are showing their potential for fewest moves. Though R'FRU:M2 can be (U2)MUM'U2M'U2M' and M':B'RB is MU'M'UMUM'.

One thing I should note is that this is LR neutral. If you really cared about the individuality of the LR edges relative to the corners, there would be another set of cases sometimes slightly different. So far I'm unsure if it matters because any Roux user experienced enough to understand this would probably know to invert a U move.

Set up: U M' U2 M2 U M' U M' U2 M U M U M U'

From the table:
U M' Three missoriented on top
U2 M U M orient
U' M' U2 M' Finish 4b


I would do:
U M U M'
U' M U' M'
U M2
Exactly. I think some of the recommended solutions are long/wrong/weird/etc. I would check them all, but I'm not good in searching alternatives.

No. As I mentioned a couple times, many don't solve the orientation and instead just solve up to the three misoriented on U case. This is a good thing because it allows you to learn only what is necessary to get to the point where you make your decision for where to place the LR edges. Instead of finishing 4a+4b with M'UM', sometimes you want to do MU2M2(UM') or something similar.

When I find the time, I'll finish the other half of this so I'll no longer have to explain that this is LR neutral.

Great work! Today I try to use it when I was solving cube - fewes moves (with Roux). At the end I redused lse algorithm by 4 moves.

But I dont understand what explain G and P? (under algorithm). For example: G8 P7
