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.
