What I was referring to was not overlap of work within GIMPS, or duplication of effort by two different GIMPS participants. I was referring to there being no agreement, at that time, to avoid duplication between (a) George Woltman and (b) the team of David Slowinski and Paul Gage (who were testing Mersennes, independently of George, on Cray computers). George Woltman just _barely_ missed out on becoming a Mersenne prime discoverer back then. (But he was not a poachee bcause there existed no reservation system between Slowinski & Gage, and him. It was just happenstance that Slowinski and Gage completed L-L testing M1257787 while George was in the midst of L-L testing that very same number.)
