Dear List,

For a rhombohedral structure, I did `initso´ after converging a non-SO calculation. `symmetso´ complains (in the last section of `outsymmetso´):

        WARNING !!!!!!
nsym found by symmetry differs from iord read in struct  12   4

Why does it say that? This would seem normal to be, since it is `symmetso´s job to reduce the symmetry.

After that:

 Symmetry operation           2
        0.50000        0.86603        0.00000
        0.86603       -0.50000        0.00000
       -0.00000        0.00000       -1.00000
        0.00000        0.00000        0.00000
   -1.0000   -0.0000   -0.0000    0.0000
    0.0000    0.0000   -1.0000    0.0000
    0.0000   -1.0000    0.0000    0.0000


           WARNING !!!!!
   this symmetry operation was not found in struct!!

This kind of thing is repeated a couple of times.  What does this mean?

The last three lines of numbers specify a symmetry operation which *is* in fact in the struct file; what are the four lines before that?

I am not very familiar with SO, nor with rhombohedral symmetry calculations, so I am unsure if it is safe to continue. The new `struct´ file created looks fine. It has 4 symmetry operations. The `ksym´ is empty, is that normal?

Wow, that was a lot of questions.  Thank you for you patience.
