(F B2 R D) //EO (4/4)
L2 D2 B D2 B F2 L //DR (7/11)
(R2 L2 * B L2 B' D2 B' D2 F) //3e (9/20)

* = L2 D2 R2 F' D2 L2 U2 B (8-3/25)

R' L (B' R) //EO (4/4)
(U) B' L2 F D' F' D //DR (7/11)
B' U2 B [1] U2 B U2 R2 //5e (7/18)

[1] = B' U2 L2 D2 F' D2 L2 [2] U2 (8-6/20)
[2] = L R' U2 L' R B2 (6-2/24)

Skeleton: R' B F2 L2 F2 D R2 L2 U' z2 R D R' U' R2 F2 R' D2 U' * B U2 D
* = L2 D F2 B2 z2 D' L2 (6/27)

(B2 U R2 U') //CO (4/4)
R D' L D2 R' D R' //CP and some edges (7/11)

On inverse with premoves R D' R D2 L' D R':
(F2 D L2 D') //Slightly different CO (4/11)
(F R' D U' B R') //2e2e3e (6-2/15)

Full skeleton on inverse:
(F2 D L2 D')
(F R' D U' B)
(D' R D2 L' D [2e2e] R')

[2e2e] = L2 F2 R2 L2 [3e] B2 R2
[3e] = R B2 U2 F2 L F2 U2 B2

25, 24, 27(25) = 25.33(24.67)
