OEIS Sequences

Principal diagonal of the convolution array A213828. A213829

Number of partitions of n into 6 or more parts. A347542

Numbers k such that the least term in the periodic part of the continued fraction for sqrt(k) is 26. A31704

a(n) = 361·n² + 19. A158592

a(n) = 169·n² + n. A173275

Array read by antidiagonals: Place k points in general position on each side of a regular n-gon and join every pair of the k·n boundary points by a chord; T(n,k) (n >= 3, k >= 0) gives the number of edges in the resulting planar graph. A392282

Number of length-n 0..6 arrays connected end-around, with no sequence of L<n elements immediately followed by itself (periodic "squarefree"), and new values introduced in order 0..6. A215399

T(n,k) = number of length-n 0..k arrays connected end-around, with no sequence of L<n elements immediately followed by itself (periodic "squarefree"), and new values introduced in order 0..k. A215401

a(n) = n^p - (n-1)^p, where p is the n-th prime. A61028
