 OFFSET 1,1 COMMENTS The sequence lists the twin amicable number pairs in increasing order. So opposite to the list of the amicable numbers, the pairs (m, n) are necessarily adjacent to each other in this list. First differs from A259933 at a(19). - Omar E. Pol, May 19 2016 REFERENCES Song Y. Yan, Perfect, Amicable and Sociable Numbers, World Scientific Pub Co Inc, 1996, pp. 113-121. LINKS Zoltan Galantai, Table of n, a(n) for n = 1..150 Bela Galantai, Software source code written in Clipper Eric Weisstein's World of Mathematics, Amicable Pair EXAMPLE The (63020, 76084) amicable pair does not qualify since it overlaps with the (66928, 66992) pair. On the other hand, 66928 and 66992 are contiguous, thus the (66928, 66992) amicable pair belongs to the sequence. CROSSREFS Cf. A002025 (smaller), A002046 (and larger of an amicable pair). Cf. A063990 (amicable numbers), A259180 (amicable pairs), A259933.
