B' R L' //EO 3
D B R2 L2 B2 U2 D' B' //DR 8/11+4
D' R2 D (U' L2 U #') //HTR 6/17
(F2 U2 #) //E+S //2/19
#: E //+0/19

new skeleton:
B' R L' //EO 3
D B R2 L2 B2 U2 D' B' //DR 8/11+4
D' R2 U (U' L2 D ) //HTR 6/17
(@ R2 D2 @) //S 2/19
@: S2 //+4/23

after writing down this solution, i noticed that the solution can be reduced
B R2 L2 B2 -> F U2 D2 B F //make 4x +1/24
(F2 B2 L2 U2 F2 B2) -> (R2 F2 B2 U2) //make 4x -2/22

new solution:
B' R L' //EO 3
D F U2 D2 F B D2 U' B' //DR 9/12+4
U' L2 D (U' # L2 D) //HTR 6/18
(R2 F2 B2 U2 #') //FINISH 4/22
#: E //-1/21
