Exclamation Team sieve #30: c156 from 283752:i7004

In the spirit of giving everyone something to keep them busy....

283752 is currently being driven by 2^3 * 3. However, 7004 is the 16th line with the driver having the form 2^3 * 3^2; accordingly, there is a 50% chance of an escape on the next line. unconnected reported doing 1.5*t55 worth of ECM work and LaurV performed the poly search.

======================================

Got a poly after about a week. Is it (relatively) good? How good? How long the sieving will take on two cores of a core2 3Gigs? (about) Can that be taken as a "one man job?" Maybe I will give it a try....
Code:
# Sieve with the 14e siever on the algrebraic side starting from 15M
