Alex,
Symexp creates object with names of the form:
prefixSSXXYYZZ
After the prefix, the first two digits SS are the symmetry
operation. The next six digits correspond to the relative integral unit
cell translation XXYYZZ *after* an initial unit cell translation
intended to bring the translated atoms back into closest adjacency.
In other words, the exact XXYYZZ will depend on the atoms in the
object, since that will determine the initial "origin" 000000
translation. Nevertheless, the actual symmetry mates displayed should
be equivalent, even if their names differ slightly.
Are you finding otherwise?
Cheers,
Warren
