L2 D2 // square (2/2) B U' B2 R B2 F2 // 223 (6/8) (B D2 B') // EO (actually also DR lol) (3/11) (L2 D' L2) // ab2c2c (3/14) Skeleton: L2 D2 B U' B2 R B2 F2 L2 D L2 @ B D2 # B' @ = L2 B R' B' L2 B R B' // ab3c (8-4/18) # = D B' U B D' B' U' B // finish (8-3/23) Didn't have enough time to exhaustively check all insertions, but I'll take it. Wouldn't surprise me if optimal inserts lead to 21 or 22 Actually I just checked, 23 is optimal here. :) IF also finds a 22 using 2c2c + 3c insertion but I don't think that's reasonable to find. This 23 was also the best solution anyone got on this scramble. It's funny how that keeps happening; my global average is much worse than you-know-who and you-know-who, but because I almost never try DR and rarely even bother with EO starts, I sometimes end up getting good results on scrambles that suck for DR. --- 2026 comment: L2 D2 B U' B2 R // EO (6/6) (B D2 B') // DR 4b5 (3/9) (L2 D' L2 F2 B2) // ab2c2c (5/14) real 6-move EO
