If someone does have the archive of that sublist, it would be a tremendous source of information for documentarians.

Hal and I and some others got to talking about the notion of a person discovering a Mersenne prime on prime95, then putting a post on the chat group we had going for that topic, offer to sell it. Then the buyer gets the number and the intermediate residuals, reports it, goes into the record books forever as the discoverer. If the seller claims he really discovered it and sold it, that doesn’t go in the record books: it is irrelevant because the other feller announced it first.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>That discussion led into the notion of an algorithm that takes a long time, finds a special set of numbers, such as discovering by brute force they key to a hash function (Hal knew the hell outta that kind of thing.) Then a prole could sell that key, in a way that is kinda analogous to what Prime95 was doing (and is still doing (with a hash function that nature gave us (and a shortcut that Lucas and Lehmer gave us.)))<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Some of that discussion is in the main list ExIchat.
