A follow up question: I used two different systems with the same point group symmetry. I used the same density of the Monkhorst Pack grid of 8x8x6. But the resultant number of reduced k vectors when using nosym=.false. and noinv=.false. are different? As mentioned in the previous post, I am

Now I apply the symmetry operation of the point group manually to the list of k points with no symmetry and try to match the output with that of the symmetry reduced k point list generated above. Did you check if some of the vectors you get are equivalent to each other minus a vector of the

Hi, I am sorry for the sloppiness. I generated a list of k points setting nosym and noinv to TRUE in scf calculation for a system with 2/m point group symmetry. I also generated the k point list with full symmetry consideration by setting the above two flags to FALSE. Apart from identity, there
