The last move should be R'.2x2x3: (L' F2 R)
My solutions from the final round of Only FMC 2017:
1st scramble: R' U' F R2 U2 R' F2 D2 F2 U2 F2 R' B' D' F' U' R2 F' U L' R U2 F' R' U' F
2*2x2x1: U2 L' F' R
Pseudo-F2L-1: D B U2 R2 D' F2
3E3C: D R B * R2 B' D2 F'
* = D' R2 D R D' R D R2 (Inverted Anti-sune)
Solution: U2 L' F' R D B U2 R2 D' F2 D R B D' R2 D R D' R D B' D2 F'
23 moves.
Comment: Once more thanks to Guus for his remark on inserting Sunes at Eat Sleep Cube Repeat 2014!
2nd scramble: R' U' F L2 F2 D2 R2 D2 R2 B2 R2 U L2 D' B' L' F U2 R U B' U2 R D2 R' U' F
EO+2x2x1+pairs: R * U B L
2x2x2: F' U2
at this point I first switched and found the following L3C: F D2 B D2 B' D2 F' R2 F' R2 F U R2 U' R2
However, after putting the skeleton together, I noticed that I could get the same L3C in a slightly shorter way:
2x2x3 + many blocks: R2 U R2 U' B' D2
L3C: B2 R2 B R2 B' R2 B' R2
* = R' F L' F' R F L F'
Solution: F L' F' R F L F' U B L F' U2 R2 U R2 U' B' D2 B2 R2 B R2 B' R2 B' R2
26 moves.
Comment: I wouldn't be too surprised if someone finds a better finish for this start.
3rd scramble: R' U' F U2 F2 U2 R2 U2 L2 R2 U' L' F2 L' U L2 B R2 F2 U' L U' R' U' F
2*2x2x1: F2 U' L U2
2x2x3: (L' F2 R')
F2L-1: D2 R' B R2 L' D' L
I did the R2 to save the other 3 move pair so that R' D2 B' D' B would give F2L. I then noticed that the OLL would skip and saw, that I could also solve the last F2L pair differently to cancel into OLL:
F2L: F D' F' D2 R'
OLL+Skip: R D F D2 F' D' F D F' R'
Luckily, the end also cancels with the inverse part.
Solution: F2 U' L U2 D2 R' B R2 L' D' L F D' F' D' F D2 F' D' F D F L
23 moves.
Comment: I guess this is what you could call "the lucky one". I certainly won't complain that everything cancelled so nicely. At this point in the solve, I already had a 25 (PB mean!!!) from a completely different start (giving L3C in 20), but this solution was definitely the ice on the cake.
23, 26, 23 = 24,00 mean of 3
A sune changes 3 edges and twitsts 3 corners. That was Sebastien's case.Sorry, but how do you insert a sune into a skeleton/solution? is that for L3E+L3C ?
(U' F' D2 R2 F2) //2x2x21)R U2 F2 U2 F2 R2 D2 L B2 F2 R2 U B U F2 R' U2 B L2
All on inverse
U' F' D2 R2 F2//2x2x2 (5/5)
B2 D'//2x2x3 (2/7)
D L2 D2 B' D//EO (5-2/12-2)
B' L2 B' L B L2 B//4C3E (7/17)
Skeleton: B' L2 B' L' B L2 B D' B D2 L2 * B2 F2 R2 D2 F U
*= U B' U' B//solve edges, leaves gj6C, cancels 1
B' L2 B' L' B L2 B D' B D2 L2 @ U B' U' B' F2 R2 D2 F U
@=B' D2 B U B' D2 B U', cancels 4
B' L2 B' L' B L2 B D' B D2 L2 B' D2 B U B' U' ! D2 B' F2 R2 D2 F U
!=U B D B' U' B D' B', cancels 4
Final: B' L2 B' L' B L2 B D' B D2 L2 B' D2 B U D B' U' B D' B' D2 B' F2 R2 D2 F U (28)
Does anyone have a better ending :/
