1. mit und ohne Limit:

EO: R B D'
Domino: F R' U2 R2 B R'
2x2x3: B' L2 B' R2 B L2 B'
L5E: L2 F2 L2 F
Rest: D2 L2 D2 F D2 L2 D2 F

Solution: R B D' F R' U2 R2 B R' B' L2 B' R2 B L2 B' L2 F2 L2 F D2 L2 D2 F D2 L2 D2 F

28 moves.

Very disappointing. I spent a lot of time with the following two skeletons without finding any better solution:

L8E: R B D' B2 L' B L F' R2 B' R' B' R B

6E3C: R B D' F R' U2 R2 B R F
