OEIS Sequences

Heptagonal (or 7-gonal) pyramidal numbers: a(n) = n*(n+1)*(5·n-2)/6. A2413

Partial sums of A007585. A51797

Least positive integer k such that prime(k)-k, prime(k)+k, prime(k·n)-k·n, prime(k·n)+k·n, prime(k)+k·n and prime(k·n)+k are all prime. A259492

a(n) is the smallest n-gonal pyramidal number with exactly n prime factors (counted with multiplicity). A358865

Numbers k such that σ(k) divides k². A90777

Larger of semi-unitary amicable numbers pair: numbers (m, n) such that susigma(m) = susigma(n) = m + n, where susigma(n) is the sum of the semi-unitary divisors of n (A322485). A322542

Numbers k that can be expressed as k = w+x = y·z with w·x = (y+z)³ where w, x, y, and z are all positive integers. A57370

Solution of the complementary equation a(n) = a(n-1) + a(n-2) + b(n), where a(0) = 1, a(1) = 5, b(0) = 2, b(1) = 3, b(2) = 4, and (a(n)) and (b(n)) are increasing complementary sequences. A295952
