Thank you TDM for response.
So I have another one: how to determine if I should do Interchange first or second when doing commutator?
Do [L D' L', U] for setup.
The interchange will be between UFR and UFL. The interchange movement will be either U or U'.
The third piece (RDF) has to go to UFR. If you place it directly to its correct place (UFR), then placement first (R' D' R), interchange last (U'). Full solution: [R' D' R, U'].
If you place it not to its direct place, but the interchange-place (UFL), then you have to interchange first (U), placement last (L D' L'). Full solution: [U, L D' L'].
