Very happy about this !!

Again couldn't save my solution as :

F2 B' L2 U R2 U2 D' F' Uw2 B2 R2 F2 R2 U' R2 D2 F2 Uw2 R' B' U' L

Double wide moves seem to be bugged

7 28 Agnar Renolen 1. D' B D2 L2 U' L' D L U L' R F2 R' F' R' F R D L D' R2 D L' R D R U2 R (28)

Pre: U2 R
2x2x2: D' B D2 L (a)
2x2x3: D R F2
EO: R' F' R' F
AB4C: R' D (b) R D R
Insertions:
(a) = L U' L' D L U L' D' (-3)
(b) = D' R2 D L D' R2 D L' (-3)

Comment: After 2x2x3, tried F' R2 F D R D for AB(5C+3E), but didn't find the 6 move insertion that would cycle the edges in place.
