OEIS Sequences

T(n,k)=Number of side-n hexagonal 0..k arrays with values nondecreasing E, SW and SE. A216937

Sum of largest parts of all partitions of n into an odd number of parts. A222047

Triangle read by rows: T(n,k) is the number of non-equivalent regular polygons with n+1 edges, one of which is rooted, which are dissected by non-intersecting diagonals into k regions, such that two such polygons are identified up to reflection along the rooted edge and twisting along the diagonals that does not affect the root edge (for 1 <= k <= n-1 and n >= 2). A232206

Engel expansion of sinh(1/2). A68379

Numbers k that have no zero digits and such that both k+1 and (product of digits of k) + 1 are squares. A81990

a(n) = (1/2+1/2·i*sqrt(11))ⁿ + (1/2-1/2·i*sqrt(11))ⁿ, where i=sqrt(-1). A131040

a(n) is the index where A387090(n) appears in A386482. A386484

a(n) = 4*(3·n+1)*(3·n+2). A144410

a(n) = ∑_{prime p <= n} n!/p!. A110378
