OEIS Sequences

Oblong (or promic, pronic, or heteromecic) numbers: a(n) = n*(n+1). A2378

Quarter-squares: a(n) = floor(n/2)*ceiling(n/2). Equivalently, a(n) = floor(n²/4). A2620

Numbers k such that 8·10^k - 49 is prime. A271269

The squarefree numbers ordered lexicographically by their prime factorization (with factors written in decreasing order). a(n) = ∏_{k in I} prime(k+1), where I is the set of indices of nonzero binary digits in n = ∑_{k in I} 2^k. A19565

Triangle of coefficients of polynomials u(n,x) jointly generated with A029653; see the Formula section. A208510

Numbers that are the product of exactly three (not necessarily distinct) primes. A14612

a(n) = ∑_k=1..n floor(n/k); also ∑_k=1..n d(k), where d = number of divisors (A000005); also number of solutions to x·y = z with 1 <= x,y,z <= n. A6218

Positive integers congruent to 2 (mod 4): a(n) = 4·n+2, for n >= 0. A16825

Sphenic numbers: products of 3 distinct primes. A7304

a(n) = prime(n) + 1. A8864
