Historical Note on the Amicable Pair $17 \, 296$ and $18 \, 416$
The amicable pair $17 \, 296$ and $18 \, 416$ were discovered by Pierre de Fermat in $1636$.
As such, it appears that he re-discovered what had previously been discovered by the medieval Arab school.
It was, however, the second amicable pair to be known of by the Western mathematical world after $220$ and $284$, known of old.
