F R U' D L' // EO
(D R2 B D) // 222
U' D F' D' // 223
(U2 F U' F' U F2 U2 F2 U F' U2) // L3C in 24
ssf: F R U' D L' U' D F' U2 D' F U' F2 U2 F2 U' F U F' * U2 D' B' R2 D'
* F' R2 F L F' R2 F L' // 8-31
solution: F R U' D L' U' D F' U2 D' F U' F2 U2 F2 U' F U F2 R2 F L F' R2 F L' U2 D' B' R2 D'

after the 223 with:
(U2 F U' F2 U F' U2 F U') I got an L5C in 24, but I didn't expect that it was good for a 30 and tried other things.
