Centered tetrahedral numbers. A5894

Numbers that are the sum of 12 positive 6th powers. A3368

Product of the 4th power of a prime (A030514) and a different prime (p⁴*q). A178739

a(n) = σ(n) * A003961(n), where A003961 shifts the prime factorization of n one step towards larger primes, and σ is the sum of the divisors of n. A341529

a(n) = a(n-1) + a(n - 1 - number of even terms so far). A6336

Number of intersections inside an equilateral triangular figure formed by the straight line segments mutually connecting all vertices and all points that divide the sides into n equal parts. If three or more lines meet at an interior point this intersection is counted only once. A92866

Triangle read by rows: row n lists number of ordered partitions into k parts of partitions of n. A60642

Smaller of two consecutive numbers each divisible by a cube greater than one. A68140

Number of integer partitions of n where the parts have the same median as the distinct parts. A360245

a(1) = 1; a(n) is smallest number > a(n-1) such that the juxtaposition a(1)a(2)...a(n) is a prime. A74336
