2. mit und ohne Limit:

Inverse:
2x2x2: D2 B2 R2
EO: L2 * F'
L3C: L F2 L' D2 L2 D2 L' D R' D2 R D'

* = L2 F' R F L2 F' R' F

Solution: D R' D2 R D' L D2 L2 D2 L F2 L' R F L2 F' R' F R2 B2 D2

21 moves.

Found this after around 15 minutes.

Also very interesting:

R L' F' R
(U D' L U2 L/L')

Domino with 2*2x2x1 in 9 moves! But I couldn't find a good finish for this.
