Taking 7p5_305.

Surprising result:

Code:

p49 factor: 3967235215334305654401809872885914731284135046311
p70 factor: 9034580254864795077049712782791019491207593302871566768644110601867251
p78 factor: 123055506362548842868623292642618363952116034086352186892461107189797972193211

As a 3rd hole, Bob should have done ECM to t55 on this number. The probability of this factor being missed by that is about 1 in 2200. Unlucky!

Also, it was way oversieved. At the end of linear algebra, msieve reported that it could only find trivial dependencies. When I cut the number of unique relations down to 130M, it was fine.
