Mistake

 * Primorial $(n) - 1$ is prime for $3$, $5$, $11$, $13$, $41$, $89$, $317$, $991$, $1873$, $2053$, and no other values below $2377$.

$337$ was omitted from the above list.

However, it needs to be pointed out that the source work that this result was quoted from (the article in by,   and , was the source of this inaccuracy:


 * The number $N = p \# - 1$ is prime for:
 * $3$, $5$, $11$, $13$, $41$, $89$, $317$, $991$, $1873$, $2053$
 * and is composite for all other $p < 2377$. The number $2377\# - 1$ is a pseudoprime whose primality has not been verified.

Interestingly, under the entry for $15,877$, does include $337$, but somehow manages to omit $13$.
