  1. I am not an expert on this.
  2. However, my strong prior would be no, since because it is "exact" it has to calculate all the possible configurations and there are a lot to calculate with the values of n1 and n2 you gave.

"Men by nature long to get on to the ultimate truths, and will often be
impatient with elementary studies or fight shy of them. If it were possible
to reach the ultimate truths without the elementary studies usually prefixed
to them, these would not be preparatory studies but superfluous diversions."
