And right as George is on vacation, until Tuesday.
Anyone know how to figure out which exponent it is?

comparing it to the stats listed might give a hint. The cleared.txt I downloaded had 6933 entries in it. The stats for the corresponding time indicated 812 factored composite, 1628 double checks and 4492 firsttime tests. With the unverified prime that gives 812+1628+4492+1 = 6933. So the prime is (probably) listed in cleared.txt. But it's not there with a residue of 0. So, if it's there, it's there with a fake residue. Since the first notice here came at 19:24 UT, it is a reasonable assumption that the result was submitted after 18:00. Sorting the firsttime tests by time produces these possibilities: Code:
32234869 69 0xB45FE198573472__ 23Aug08 18:59 raistlin078♦ 41125727 75 0xCF6D113C931A1A__ 23Aug08 18:40 edfox ♦ 32862211 68 0xFD2FB401271F0B__ 23Aug08 18:37 linded ♦ 43039897 70 0xC406DB93EF918C__ 23Aug08 18:30 AO ♦ 31714931 69 0xD17567F80D80BE__ 23Aug08 18:25 ahmerali ♦ 39598231 69 0xC6A9494D6AF911__ 23Aug08 18:16 dstoops ♦ 17634277 66 0x74561216DE9ADB__ 23Aug08 18:04 shaneamy ♦ as it makes certain assumptions about the timing of the unverified prime posting.

WOW! The legendary 10M digit prime was probably finally found!
Isn't there an hourly archive of PrimeNet's files somewhere? Where is that? Last fiddled with by MiniGeek on 20080823 at 23:57

And since 4/7 of the numbers given by Graff are less than 10M I would think it would be better to use the word "possibly" rather than "probably". A minor detail of course, but pedantry is one of my hobbies.
