Dear QE users,
I am running a SCF calculation on La2CuO4 using a 8x8x8 Monkhorst-Pack
grid and using the spacegroup keyword to use the full symmetry. The
program runs correctly and the SCF output file says that it generated 59
k-points. But if I look at the La2CuO4.save directory, there are 105
different wfcN.dat files.
My understanding was that there was one wfcN.dat file per k-point, so I
don't understand the reason there are more than 59 in this case.
I am using QE-6.8.
