Carmichael Number with 4 Prime Factors

Theorem
$41 \, 041$ is the smallest Carmichael number with $4$ prime factors:
 * $41 \, 041 = 7 \times 11 \times 13 \times 41$

Proof
From Sequence of Carmichael Numbers:

The sequence continues:


 * $\ldots, 29 \, 341, 41 \, 041$

We now investigate their prime factors:
