a(n) = number of partitions p of n such that the greatest multiplicity of the parts of p is a part of p. A365613

Numbers k with more than one maximum clique containing k in the gcd-graph of {1, 2, ..., k}. A387699

Triangle read by rows: T(n,k) is the number of deco polyominoes of height n having k cells in the second column (n>=1, k>=0). A deco polyomino is a directed column-convex polyomino in which the height, measured along the diagonal, is attained only in the last column. A121581

a(n) = denominator(b(n)), where b(0) = b(1) = 1 and b(n) = n·b(n-1)/b(n-2) for n >= 1. A329813
