| Sep 18, 2014 at 17:49 | comment | added | Yemon Choi | The question in its current form still seems to be off-topic, for the reasons given by those who voted to close. | |
| Sep 18, 2014 at 17:46 | comment | added | Yemon Choi | The new title is incorrect, or based on faulty understanding: search online for "Carmichael number". | |

| Sep 18, 2014 at 13:04 | comment | added | KConrad | You say a certain congruence works for all $a$ and some $n$ but do not give examples. Why not help readers by including the first few $n$ in your question? With a computer I find the only $n \leq 3000$ that work are 1, 2, 6, 42, and 1806. At oeis.org, this is A014117. | |
