• a(n)=a(n-1)+a(n-2)-d, where d=a(n/4) if 4 divides n, else d=0; 2 initial terms.at n=29A050194
• G.f. satisfies: A(x) = Sum_{n>=0} binomial(n*(n+1),n)/(n+1) * x^n/A(x)^n.at n=6A295763
• a(n) = a(n-1) + a(n-2) + 2 a([(n-1)/2]), where a(0) = 1, a(1) = 1, a(2) = 1.at n=26A298354
• Positive numbers k such that the centered cube number k^3 + (k+1)^3 is equal to the difference of two positive cubes and to A352759(n).at n=25A355751
