Triple Checks would be appreciated on the following CuLu results:
Code:
DoubleCheck=36848387,71,1 DoubleCheck=38671361,71,1 DoubleCheck=66921341,74,1 DoubleCheck=64847711,75,1 Last fiddled with by UBR47K on 20160106 at 01:48

Based on a discussion elsewhere in the forum: madpoo, do you have the database access sufficient to produce a list of numbers where the reported residue is 00000000000000__ ?

My goal was to a) satisfy my own curiosity and b) prevent the speculation that would occur if someone saw a masked residue like that. EDIT: Examples: M66921341 M62891251 M79060367 (trust me when I say the masked part is NOT "00") Last fiddled with by Madpoo on 20160107 at 23:20

Unless I am misreading the status page something rotten, 79060367 hasn't been doublechecked and is not assigned to anybody.
Nearlyallzeroes residue nearly always means 'the FFT data got zeroed at some point' (possibly 'a checkpoint file was written while the disc was full and then prime95 restarted from the allzeroes checkpoint')

Third, even if all are zero, it may not mean that the number is prime. This is only the tail of the full residue. Statistically, we can get a result with all the last 16 hex digits being zero every 18,446,744,073,709,551,616 exponents...

Eventually it'll get double and triple checked, but it's clear the first test was bad.
