48th Mersenne prime found
I went to this university and took several of Professor Cooper's classes.  He was a great guy and he seemed really passionate about his Mersenne project.One thing that was annoying however was the prime finding software was put on every lab computer possible.  It was suppose to pause when a user got on a machine and resume when they got off.  This seemed to never be the case though because they would all run terribly slow and when you checked the process list the prime software would be pegging the CPU. After reporting the problem several times I simply added a line in my bash file to kill it when I logged on.
