[Wien] k-points of doped material

As I said, the first structure is F (press f3 in xcrysden and you will see the primitive cell) the second structure is P (if you press f3 nothing will happen in xcrysden).

So the P structure is 4x larger.

Sorry, I was wrong with the counting in the last mail, in the F cell you have 4 atoms and in the P you have 4x4=16

So, volume of P reciprocal cell is 1/4

Yes
I am working on X2YZ heusler with Fm-3m spacegroup.I am trying to create X2YZ 0.5 R 0.5 structure. When i run the supercell by 1*1*1 cell it convert to P spacegroup with separated position.After x sgroup running it change to P4/mmm structure. Now is the second one bigger? and did it need to less k-points (how many)? how can i find that the second one is bigger?
