[Wien] equavalent atoms and memory/speed

[Michael Gurnett]

I been wondering about this. Does one gain or loose in speed or in memory when using equavalent atoms. I have a slab now that has 70 atoms. I have 35 lots of 2 pairs of equavalent atoms. Am I gaining by this or am I better of labeling them so that I have 70 individual atoms. What are the pros and cons between the two cases.

Best wishes
