Hello all ! I have a request to all of you, and please don't laugh. What do you think about a project to find a prime 6-tuplet>1100 digits ? My calculate, we...

It appears likely that every prime can be written as the sum 1a^2 + 2b^2 + 3c^2, for a,b,c >= 0. For instance the prime 61 can be expressed in two such ways: ...
Has anyone looked at prime chains, parallel to Cunningham chains, of the form 2^n+/-k? Such a chain would be prp for fixed k, with n in the chain increasing by...
... Another example: Consider the (already known) prime poly 36x^2 - 810x + 2753 which produces 45 consecutive primes (including negatives) from x=0 to x=44. ...

Hi All, The new LLR 3.7.0 Version is now available on the GIMPS directory! It contains as a new important feature an efficient primality proving test for the...
If you could prove that the convergence upon Li(x) (or even x/log(x)) becomes increasingly such (i.e., the more convergent it becomes, the more convergent it...

Only a comment. If you want to prove a polynomials P(x) is prime, isnt enough to determine the assoiated roots. E.g. P(x)=x^2+2 The number N is P(x) which can...
... As you know, Gauss was the first to establish that the number of primes < x, pi(x), is approximately equal to the logarithmic integral of x, Li(x), for...
