a(1) = 1; thereafter a(n) = 6*(2^n-1 - 1). A68293

Smallest number m such that σ(m) is an n-almost prime. A152092

Triangle read by rows: denominator of h(n-k)*h(k)/h(n) where h(x) = ζ(2·x)*(4^x-2), 0<=k<=n. A246052

Start with a single triangle; at n-th generation add a triangle at each vertex, allowing triangles to overlap; sequence gives number of triangles in n-th generation. A61776

a(n) = min{ m : ∑_{n <= i <= m} 1/p_i > 1}, where p_i is the i-th prime = A000040(i). A92325

Number of ways that a 1 X n rectangular tile T, marked into n unit squares, can be surrounded by one layer of copies of itself laid in the plane grid generated by the units of T. Ways that differ by rotation or reflection are not counted as different. The surrounded tile is the exact surrounded region. A159294

Base-10 representation of numbers k which, in base 2, satisfy abs(k + reverse(k) - reverse(k + reverse(k))) = abs(k - reverse(k)) + reverse(abs(k - reverse(k))) = k. A179697

Even integers k such that φ(sum of even divisors of k) = sum of odd divisors of k. A281707

Consecutive states of the linear congruential pseudo-random number generator 228·s mod (2¹⁶+1) when started at s=1. A385079
