**Jean-Marie Hachey**: Quadratic equations giving primes. Prime numbers being only positive, it is evident that only eqn [1] by Euler will produce specifically sequences of...**Matthew Gladback**: This solution can be sharpened a good bit. As I'm a C++ programmer, I'm not sure if all these suggestions translate to C#. You can get mod-4 results...**nuri**: woah! after finding solution using brute force, I tried jeras' method (in c++) it gave me: sum 518408346 elapsed 0.000033 ms damn that's fast tim...**Jean-Marie Hachey**: @ baurLychrel numbers https://oeis.org/A023108...**baur**: Do we have a list of these numbers somewhere?...**Eldar**: This is brilliant. I made the mistake of trying to do this problem using the principles from the sieve or erastothenes and a humongous array. Thanks t...
