OEIS Sequences

Triangle T(n,k) = Number of k-cycles on the graph of an n-orthoplex. n>=2, k>=3. A167986

Let h(m) denote the sequence whose n-th term is ∑_k=0..n (k+1)^m*T(n,k)², where T(n,k) is the Catalan triangle A039598. This is h(6). A228332

4·a(n) is the maximum possible determinant of a 3 X 3 matrix whose entries are 9 consecutive primes starting with prime(n). A340923

Let·be the sum of the divisors d_i of k such that d_i | σ(k). Sequence lists the numbers k for which x² = σ(k). A284283

a(0)=1. a(n) = sum of the earlier terms which are divisible by (the number of 1's in the binary representation of n). A123757

Expansion of e.g.f. tanh(arctan(x) * exp(x)). A12415

Table read by antidiagonals: T(n,k) (n >= 3, k >= 1) is the number of vertices formed in a regular n-gon by straight line segments when connecting the n corner vertices to the points dividing the sides into k equal parts. A354544

a(n) = (s(n) + 9)/10, where s(n) is the n-th base 10 palindrome that starts with 1. A43080
