Amicable Pair/Sequence

Sequence

The sequence of amicable pairs begins:

$\tuple {220, 284}, \tuple {1184, 1210}, \tuple {2620, 2924}, \tuple {5020, 5564}, \tuple {6232, 6368}, \tuple {10744, 10856}, \tuple {12285, 14595}, \tuple {17296, 18416}, \tuple {63020, 76084}$

This sequence is A259180 in the On-Line Encyclopedia of Integer Sequences (N. J. A. Sloane (Ed.), 2008).

The sequence of the $1$st elements is A002025 in the On-Line Encyclopedia of Integer Sequences (N. J. A. Sloane (Ed.), 2008).
