• Let Do(n) = A006566(n) = n-th dodecahedral number. Consider all integer triples (i,j,k), j >= k > 0, with Do(i) = Do(j) + Do(k), ordered by increasing i; sequence gives k values.at n=25A053019
• Numbers n such that sigma(n) = 2*(n-reversal(n)).at n=8A135242
• Sum of the asymmetry degrees of all compositions of n with parts in {1,5}.at n=35A276065
• p-INVERT of (1,0,0,0,1,0,0,0,0,0,...), where p(S) = (1 - S)^2.at n=28A292325
• Triangle read by rows: T(n,w) is the number of n-step self avoiding walks on a 3D cubic lattice confined inside a tube of cross section 2w X 2w where the walk starts at the center of the tube's side.at n=22A337401
• G.f. A(x) satisfies: A(x) = x * exp(2 * Sum_{k>=1} (-1)^(k+1) * A(x^k)^2 / (k*x^k) ).at n=6A363390
