• Theta series of lattice D3 tensor D3 (dimension 9, det. 4096, min. norm 4).at n=12A033693
• Reversible Lynch-Bell numbers.at n=26A117954
• a(n) = [x^n] G(x)^(2^(n+1)) where G(x) satisfies: [x^(n+1)] G(x)^(2^n) = [x^n] G(x)^(2^n) for n>=0 and G(2x) is the g.f. of A134084.at n=4A134087
• Triangle read by rows: T(n,k) is the number of weighted lattice paths in L_n having k returns to the horizontal axis (both from above and below). The members of L_n are paths of weight n that start at (0,0) , end on the horizontal axis and whose steps are of the following four kinds: an (1,0)-step with weight 1, an (1,0)-step with weight 2, a (1,1)-step with weight 2, and a (1,-1)-step with weight 1. The weight of a path is the sum of the weights of its steps.at n=48A182898

• Numbers k such that 427*2^k+1 is prime.at n=36A323114
