We should all aspire to excellence in BS, and one of our many sources of information should include knowing all the gossip about every number we use.

This post will probably be 34561. 561, now, just for example, is square free AND a Carmichael number, a sort of pseudo-prime.

"The composite integer n is a Carmichael number if bn-1 = 1 (mod n) for every integer b which is relatively prime with n.

Carmichael numbers behave like prime numbers with respect to the most useful primality test, that is they pretend to be prime."
