좋은 프라임

Good prime

좋은 소수는 소수 순서에서 그 전후의 같은 수의 위치에 있는 두 소수의 곱보다 제곱이 큰 소수입니다.

즉, 좋은 소수는 불평등을 만족시킨다.

pk k번째 소수입니다.

예: 첫 번째 소수점은 2, 3, 5, 7, 및 11입니다.5에 대해 두 조건 모두

5는 좋은 소수입니다.

좋은 [1]소수점들이 무한히 많다.처음 좋은 소수점 몇 가지는

5, 11, 17, 29, 37, 41, 53, 59, 67, 71, 79, 97, 101, 107, 127, 137, 149(OEIS의 시퀀스 A046869).
