Solving of corner orientation and permutation, without regard to the M-slice edges or U layer corners. This is Step 3 of the Roux Method. Similar to CLL. It will always have a lower movecount than COLL.
One suggestion for improving this step is to use it in order to influence the orientation or permutation of edges in LSE (in particular avoiding 6-flips and encouraging EO skips or Arrow cases).
One suggestion for how to do this is Pinkie Pie or BLS (though this is not for the Roux method)
