[e] U L' B2 [c] L' F2 U' L' //Square and 222 (7/7)
U2 L' B' U' B L F //3e3c (7/14)

[e] = F' U' D R2 U D' F' (7/21)
[c] = F R2 F' L F R2 F' L' (8-1/28)

Scramble: R' U' F D' U L2 R2 F2 R2 U R2 U R U L D' B2 L2 B R' F L D' B' R' U' F
Solution: B U' D R F L2 D2 F2 D2 F U2 B' D2 B U' R2 U' B2 F2 R2 (20)

B U' D R //EO (4/4)
(R2 F2 B2) //Setup (3/7)
(U R2 U') //DR (3/10)
(B' D2 L2 F2 L2 B F' L2 F') //3c (9/19)

The last part can be shortened to 17 to 3c + 3 E-layer edges, so here I'm hoping to find a decent 3c insertion in the DR part, so I can later shorten it with slices. Even a bad 3c insertion in the DR part che lead to 2 extra moves cancelled. But today is my lucky day:

Skeleton:
B U' D R
F L2 [2a] F B' L2 F2 L2 [c] D2 B
U R2 U' B2 F2 R2

[c] = B [2b] U2 B' D2 B U2 B' D2 (8-5/22) WOW!
[2a] = S
[2b] = S'

The solution without insertions is not hard to find directly:
B U' D R //EO (4/4)
(R2 F2 B2) //Setup (3/7)
(U R2 U) //DR (3/10)
(B' D2 B U2) //222 (4/14)
(F' D2 F2 D2 L2) //Finish (6/20)
