Daniel Larsen proved a key theorem about Carmichael numbers — strange entities that mimic the primes. “It would be a paper that any mathematician would be really proud to have written,” said one mathematician.
Small Carmichael numbers are rare and here are a few 561, 1105, 1729, 2465, 2821, 6601, 8911, 10585, 15841, 29341, 41041, 46657, 52633, 62745, 63973, and 75361.
A Carmichael number is an odd composite number which satisfies Fermat's little theorem. It passes the Fermat Primality test but it's not a Prime. It's a Pseudoprime.
