Numbers j such that σ(σ(j)) = k·j for some k. A19278

Let sigma_m (n) be result of applying sum-of-divisors function m times to n; call n (m,k)-perfect if sigma_m (n) = k·n; sequence gives the (2,7)-perfect numbers. A19284

a(n) = n* - 2^n-1, where n* (A003418) = least common multiple of the numbers [1,...,n]. A59794

a(n) = n* - 2ⁿ, where n* (A003418) = least common multiple of the numbers [1,...,n]. A67068

Subsequence of terms of A019278 whose sum of divisors is also a term of A019278. A292949

a(n) = ∑_k=0..n-2 T(n,k) * T(n,k+2), with T given by A026659. A26978
