Appears in sequences
- Amicable triples. Sequence gives sigma values: A125490(n) + A125491(n) + A125492(n).at n=20A137231
- Number of length n 0..1 arrays with each partial sum starting from the beginning no more than one standard deviation from its mean.at n=20A244781
- Numbers k such that k = Sum_{i=1..j} (d_i mod d), where d_i are their aliquot parts and d is one of them.at n=24A265646
- Numbers k with at least two divisors d for which sigma(k) = d*sigma(d).at n=1A344102
