• a(n)=a(n-1)+a(m), where m=2n-2-2^(p+1) and 2^p<n-1<=2^(p+1), for n >= 4.at n=36A050059
• Number of conics which pass through 3 points and are bitangent to a general curve of order n.at n=16A060783
• A Pell-related fourth-order recurrence.at n=8A084155
• Construct sequences P,Q,R by the rules: Q = first differences of P, R = second differences of P, P starts with 1,3,9, Q starts with 2,6, R starts with 4; at each stage the smallest number not yet present in P,Q,R is appended to R. Sequence gives P.at n=53A225385
• Sum of all parts of all overcompositions of n.at n=9A236626
• G.f. A(x) satisfies: A( 2*A(x)^2 - 24*A(x)^3 ) = 2*x^2.at n=4A369531
