问题如标题所述。我想知道如果$\存在$无限多素数三元组美元(p,q,r)$这样的话\开始{方程式}p^q+q^r+r^p\结束{方程式{是质数。
编写了一些代码,发现对于素数$200$,$(3, 5, 11), (3, 5, 107), (3, 11, 131), (3, 13, 61), (3, 17, 107), (3, 17, 113), (3, 23, 167), (5, 11, 43), (5, 29, 127), (5, 41, 67), (5, 53, 109), (5, 67, 71), (5, 79, 149), (11, 23, 127), (11, 53, 109), (11, 67, 79), (11, 103, 109), (11, 137, 163), (13, 41, 43), (13, 41, 59), (13, 107, 109), (13, 131, 179), (17, 19, 41), (17, 37, 199), (17, 53, 79), (19, 23, 83), (19, 47, 61), (19, 67, 113), (19, 103, 191), (23, 31, 37), (23, 43, 73), (23, 43, 109), (23, 97, 101), (23, 131, 181), (29, 31, 131), (29, 61, 137), (31, 47, 157), (31, 59, 113), (37, 97, 173), (41, 67, 113), (43, 47, 71), (43, 89, 193), (43, 179, 181), (47, 79, 163), (47, 167, 181), (61, 67, 113), (61, 71, 127), (61, 101, 131), (79, 83, 103), (83, 127, 151), (89, 137, 151), (97, 131, 197), (103, 107, 139), (107, 151, 167), (113, 151, 173), (113, 151, 179), (163, 167, 197), (181, 191, 197), (191, 193, 199)$满足给定条件。
优点:将这个问题扩展到素数集的长度2亿美元+1$.
