Amicable Pair/Examples/2620-2924

Example of Amicable Pair
$2620$ and $2924$ are the $3$rd amicable pair:
 * $\sigma \left({2620}\right) = \sigma \left({2924}\right) = 5544 = 2620 + 2924$

Proof
Let $s \left({n}\right)$ denote the aliquot sum of $n$.

By definition:
 * $s \left({n}\right) = \sigma \left({n}\right) - n$

where $\sigma \left({n}\right)$ denotes the $\sigma$ function.

Thus:
