Oh yea! in that case I’m changing the EO to eocross and with a pseudo cross so it doesn’t take too much time. Also, yea I‘m gonna change the coll to cll.What do you do if the pair edges are trapped in DF or DB? (DL and DR are also problematic, albeit a bit less so.)
Also you can probably find better CLL algs if you're only preserving pairs and EO, eg. F R2 U' R2 U R2 U R2 F'.
