my secret-spilling tutorial
to understand this one line forger's recipe:
x^16 + x^8 - 1
Of course were you to add gcd(x^16+x^8-1,n)==1, in September,
the Gremlins would work with different cosines.
- Tao, Harcos, Englesma, et al seem to have stalled trying to improve Zhang's upper
bound of 70,000,000. They claim to have confirmed they got it down to 5414 but look
like they aren't going to be able to go much further (perhaps can push it a bit below 5000
if combine all their juice?).
