3. mit und ohne Limit:

Inverse:
EO: U L R2 * D' R'
2x2x3: B' D2 F' U L2
L3C: U' F U2 F U F' U2

* = L' D' R2 D L D' R2 D

Solution: U2 F U' F' U2 F' U L2 U' F D2 B R' D L' D' R2 D R2 U'

20 moves.

Mean: 24, 27, 20 = 23,66

Edit: Oh same solution as Jan and Ranzha. Not too surprising I guess, I didn't see any nice start on the scramble at first so I tried lots of different EOs, which they probably did as well.
