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

a(n) = ∑_{d divides n} q(d), where q(d) = A000009 = number of partitions of d into distinct parts. A47966

Numbers that are products of 5 primes (or 5-almost primes, a generalization of semiprimes). A14614

a(n) = 2·n*(2·n-1). A2939

a(n) = n*σ(n). A64987

Numbers m such that ∑_k=1..m (<1/2 + k·r> - <k·r>) = 0, where r=sqrt(2) and < > denotes fractional part. A194368

Self-Fibonacci numbers: numbers k that divide Fibonacci(k). A23172

Untouchable numbers, also called nonaliquot numbers: impossible values for the sum of aliquot parts function (A001065). A5114
