The Dictionary
$29,351$


Mistake

[$29,351$ is] Simultaneously a pseudoprime in bases $2$, $3$, $5$ and $7$.


This appears to be a misprint for $29,341$.


It remains to be seen whether the mistake came originally from 1989: Paulo Ribenboim: The Book of Prime Number Records (2nd ed.), or whether it was transcribed incorrectly from there into Curious and Interesting Numbers, 2nd ed.
