A small premium

I have run that program now for 24 hours. Whereas Mathematica was checking 1.5 billion numbers per day in the greater-than-100-billion search-range, this search has managed to look at 1.8 billion numbers in its first day (it's at 27 billion) — because factoring smaller numbers takes less time. In spite of that small premium, it'll still take until mid-March to complete the run to 100 billion. This is, nevertheless, a significant improvement over my previous estimate of August-or-so, had I not had access to the new iMac.
