Shouldn't people who want the $100,000 primeprize be going to Fatphil for help?
Maybe I'm just being a retard monkey for asking this, but since Fatphil's methods seem to yield more primes for less work, shouldn't people be attempting to either recruit him or imitate some of the stuff he does?
Not having a clue how Phi(x,y) works, or what it means, I'm willing to be told it doesn't apply, but I'm a little curious.

The FFT's Phil is using don't work for numbers of that size and they probably won't anytime soon.

I, with my Phi(3*2^t,b) am merely imitating Yves Gallot, and his GFN (Phi(2^n,b)) project. By virtue of the fact that my calculations take place in the Eisenstein integers rather than the Gaussian integers (or transformed floating point approximations thereto), my code _has_ to be slower than Yves', as I _have_ to do more work than him (mapping between the 2 spaces). That's not to say that I defer entirely to Yves in this field. I've recently achieved something that, after several months of discussion and trial and error (all error) a few years back, Yves concluded was impossible. Fortunately I'm more stubborn than him.

I only understood part of what Fatphil said, but I got the answer I was seeking. Having a math education that was cut way short, I'm hoping my college can help me get the understanding I want in, maybe, 5 years. I love math, but my government check I get(because of mental illness) is very small.

Eisenstein integers are x+wy where x and y are integers, and w is the complex cubic root of 1. See the project logo for a definition of w.
