Thanks, and actually after the solve (during writing a
solution to submit) I noticed that.
I recognized it as a pair 3-cycle with a setup, i.e.,
D' (U' Lw2 U R U' Lw2 U R') D
and AUF. However, in order to save 2 moves by this,
I had to notice that before finishing F2L (because U U' is
not counted as 0 move in the linear solve regulation) and
I'm sure I did finish F2L before investigating the LL status...
Anyway I'm looking forward to seeing your solution in FMC477.
Don't forget to insert a backslash before ' in your comments!
EDIT: FYI, there's problem in submission, see my post.
After your advise, I submitted my solution once more just to be sure it would show up. Guess what? It wouldn't show. Can you make it more explicit how the Quote text has to be formatted? Such problem was not on fmc.mustcube.net in the past.
This is my solution that I posted for FMC #477
D L' U B' R' U' R U' R' B' U' B R F L' U' L' D2 L U L' D2 U' L2 (24)
On inverse scramble with pre-move D':
2x2x2: L2 U@ L2 F'
2x2x3: (R') B' U B (R) where inserted moves help with next corner-edge pair
all but 3 corners: U R' U R B U' L and undo premove D'
insert at @: D2 L U' L' D2 L U L'
I hoped for better move cancellations.
