Appears in sequences
- Nearest integer to 1/(Sum_{k>=n} 1/k^4).at n=22A083559
- a(n) = Sum_{k + l*m <= n} (k + l*m), with 0 <= k,l,m <= n.at n=25A106846
- L.g.f.: Sum_{n>=1} a(n)*x^n/n = log( Sum_{n>=0} x^(2^n-1) ).at n=24A162415
- Position of n-th appearance of 2n in the sequence of prime gaps (A001223). If 2n does not appear at least n times, set a(n) = -1.at n=29A356223
