and left off with 2^2 * 7 or 2^4 * 31. These have the best chance
of escape of the six main drivers. 92898 had the downdriver
from 107 to 100 digits May 2nd to the 4th of 2006 and was at
2^2 * 7 * c100 sz 102 when I abandoned it May 8th. Ten lines
after resuming computations on Saturday, it escaped its driver
and soon captured the downdriver at 103 digits, leading to an
eventual termination at index 5063. I've uploaded the finished
file to the database.
