Thanks Sebastien,

Since I am looking for the most accurate possible triangulations, and 
calculations that don’t crash or compute incorrect results (after, possibly, 
months of runtime), should I use Homogenous_d? 

Is mpz_class an appropriate substitute for leda_integer under these 
conditions, or should I go obtain LEDA?

I also looked at using the Epick_d kernel, but it does not appear to be 
present in CGAL 4.4.
