One example of creating a list of primes is to create a list which has the first N prime numbers. 14p 1 1 (mod p2): 29, 353, 7596952219 (OEIS:A234810) 15077 15083 15091 15101 15107 15121 15131 15137 15139 15149 Overall, every one of the 5 places of a 5-digit number can be filled up in ten ways, because it can have 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9. 86293 86297 86311 86323 86341 86351 86353 86357 86369 86371 Odd primes p that divide the class number of the p-th cyclotomic field. They are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149]. Since its last digit is not 0 or 5, the number is also not divisible by 5. 26813 26821 26833 26839 26849 26861 26863 26879 26881 26891 14207 14221 14243 14249 14251 14281 14293 14303 14321 14323 The first 10 primes that are not cluster primes are: 2, 97, 127, 149, 191, 211, 223, 227, 229, 251.
