The Puzzlers

I am a mechanical engineer, graduated from ZheJiang University of china, studied mechanical engineering. I work for a small machine imp&exp company of LiangXi.

Since 1980 I interest the prime and mathematical Logic as hobbies. The work only published was that “the sentence x^2 – x + 72491 assumed primes for x=0,1,2,……,11000 (Hua Lugan) is false”.

Now, I posted  “A prime formula” on My paper “A weaker conjecture of prime k-tuples” as another solution of conjecture 17# was added on by Carlos Rivera. I try attack the conjecture of prime k-tuples. Wish to win the mountaintop. Lately I bought a old PC and am learning operation.
