2. mit Limit

I had 19 to good 6C but my skeleton was written down wrong, so I used this instead. Optimal for the 6C was 30 non-nested :/

F B R' D F' R //222
(F' D2 L F2) //223
(D' L D2 B' L2 B) //F2L-1
(D2 B D B') //F2L
(B' D' L' D L B) //3C (25)

sk: F ^ B R' D F' R B' L' D' L D B2 D' B' D2 B' L2 B D2 L' D F2 L' D2 F
^ = F R F' L2 F R' F' L2

solution: F2 R F' L2 F R' F' L2 B R' D F' R B' L' D' L D B2 D' B' D2 B' L2 B D2 L' D F2 L' D2 F (32)
