Two number theory questions
1. How many primes <= 12^n which is == k mod 12? For each values n = 10, 11, 12 and k = 1, 5, 7, 11
2. Find all Kaprekar's cycles for 9-digit to 12-digit dozenal numbers (a Kaprekar's cycle for 8-digit dozenal numbers is {4210XX98, X9737422, 87428744, 64328876, 652EE866, 961EE953, X8428732, 86528654, 6410XX76, X92EE822, 9980X323, X7646542, 8320X984, X7537642, 8430X874, X5428762, 8630X854, X540X762, X830X832, X8546632, 8520X964, X740X742, X8328832, 86546654}) |
