• Diagonal sums of triangle A110324.at n=50A110326
• Triangle read by rows: n-th diagonal (from the right) is the sequence of (signed) differences between pairs of consecutive terms in the (n-1)th diagonal. The rightmost diagonal (A136562) is defined: A136562(1)=1; A136562(n) is the smallest integer > A136562(n-1) such that any (signed) integer occurs at most once in the triangle A136561.at n=45A136561
• Leftmost column of triangle A136561.at n=9A136563
• Second differences of A000463; first differences of A188652.at n=50A188653
• First differences of number of active (ON, black) cells in n-th stage of growth of two-dimensional cellular automaton defined by "Rule 313", based on the 5-celled von Neumann neighborhood.at n=21A271203
• First differences of number of active (ON, black) cells in n-th stage of growth of two-dimensional cellular automaton defined by "Rule 441", based on the 5-celled von Neumann neighborhood.at n=23A272224
• Euler characteristic (H_*(h_{oo,1}^+)_{2n}^{Sp}) of the Sp-invariant homology group of the Lie algebra h_{oo,1}^+ of weight 2n.at n=9A323283
• Product_{n>=1} (1 + x^n)^a(n) = 1 + Sum_{n>=1} mu(n)*x^n, where mu = A008683.at n=31A353927
