The Carmichael numbers under 100,000 are
561, 1105, 1729, 2465, 2821, 6601, 8911, 10585, 15841, 29341, 41041, 46657, 52633, 62745, 63973, and 75361.
Small Carmichael numbers are rare: there are only 2,163 are less than 25,000,000,000. (Recently, Richard Pinch has found that there are still only 246,683 Carmichael numbers below 10,000,000,000,000,000.) Nevertheless, in 1994 it was proved that there are infinitely many of them!
