Before any number in front of K, the number of prime numbers in the form of 4n+1 i s no more than 4n-1; 2. After this number k, the number of prime numbers in the form of 4n-1 is no more than the number of primes in the form of 4n+1. This paper proves that there is a conclusion about this conjecture: 1. There is a critical point K, and the number of 4n+1 primes before any natural number in front of k is not more than 4n-1.2. There is no critical point, the number of 4n+1 primes is never more than 4n-1 primes. One of the two conclusions must be true.</li></ul>/MC/paperinfo/55547.shtmlMathematical Computation /MC/paperinfo/55547.shtml
