Appears in sequences

• Numbers k such that the least term in the periodic part of the continued fraction for sqrt(k) is 26.at n=18A031704
• a(n) = 361*n^2 + 19.at n=13A158592
• a(n) = 169*n^2 + n.at n=18A173275
• Principal diagonal of the convolution array A213828.at n=21A213829
• 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.at n=10A215399
• Number of partitions of n into 6 or more parts.at n=37A347542
• 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.at n=46A392282
