• A measure of how close r^n is to an integer where r is the real root of x^3-x-1, i.e.. r = (1/2 + sqrt(23/108))^(1/3) + (1/2 - sqrt(23/108))^(1/3) = 1.3247.... (Higher absolute value of a(n) means closer, negative means less than closest integer.)at n=51A084252
• Numerator of Bernoulli(n, -3/4).at n=5A157860
• Let f(x) = 1 + x^2 + x^4 + x^5 + x^6 + x^10 + x^11; sequence has g.f. g(x) = 1/(x^11*f(1/x)).at n=27A157876
• Stirling transform of the first kind of the Lucas numbers A000032.at n=7A213593
• First differences of number of active (ON, black) cells in n-th stage of growth of two-dimensional cellular automaton defined by "Rule 443", based on the 5-celled von Neumann neighborhood.at n=29A272228
• E.g.f.: exp(1 + x + x^2/2! - exp(x)).at n=10A293038
