Good point, and you are right, but we also have to be careful, and not get away from the relevance to LLK4.
Lucas: Do you have any ideas for a suitable naming system that could be used to specify (by its name alone) any big-cube edge perm case? Right now, without diagrams, or whole cube representations, it is (and is going to be - once the algs start rolling in) rather hard to communicate what cases are being referred to.
You can number the edges if you want.
Also, do you mean edges or wings?
