• Triangle read by rows: T(n,k) is the number of unlabeled simple graphs on n vertices with domination number k.at n=38A263284
• Partial sums of the number of active (ON, black) cells in n-th stage of growth of two-dimensional cellular automaton defined by "Rule 33", based on the 5-celled von Neumann neighborhood.at n=39A269812
• G.f. A(x) satisfies: Series_Reversion( A(x)/(1 - i*x + A(x)^2) ) = A(x)/(1 + i*x + A(x)^2), where odd function A(x) = Sum_{n>=1} a(n)*x^(2*n-1) and i^2 = -1.at n=7A277179
