OEIS Sequences

a(n) = numerator of harmonic number H(n) = ∑_i=1..n 1/i. A1008

Numbers k such that the difference between k-th prime and next prime is 70. A116493

a(n) = (1/1 + 1/2 + ... + 1/n)*lcm{1,2,...,n}. A25529

Consider the Diophantine equation x³ + y³ = z³ + 1 (1 < x < y < z) or 'Fermat near misses'. Sequence gives values of z in monotonic increasing order. A50791

Denominator of the harmonic mean of the first n positive integers. A175441

Numbers k with the property that it is possible to write the base 2 expansion of k as concat(a₂,b₂), with a₂>0 and b₂>0 such that, converting a₂ and b₂ to base 10 as a and b, we have σ(a) + σ (b) = σ(k) - k. A258813

Numerator of n·HarmonicNumber(n). A96617

Numerator of the n-th harmonic number H(n) divided by (n+1); a(n) = A001008(n) / ((n+1)*A002805(n)). A2547

Triangle of numerators in the square of the matrix A[i,j] = 1/i for j <= i, 0 otherwise. A119947

Denominator of H(n)/H(n-1), where H(n) is the n-th harmonic number = ∑_k=1..n 1/k. A193758
