• a(n) = Sum_{i=0..n} Sum_{j=0..n} T(i,j), T given by A026747.at n=13A026756
• Denominators of continued fraction convergents to sqrt(427).at n=11A041813
• Positive integers n that are palindromic in base 2 and whose binary representation has the same number of 0's as 1's.at n=32A143905
• Triangle of sums of the first k n-th powers multiplied by binomial(n,k), read by rows.at n=57A215078
• Place n equally spaced points around the circumference of a circle and then, for each pair of points, draw two distinct circles, whose radii are the same as the first circle, such that both points lie on their circumferences. The sequence gives the total number of vertices formed.at n=24A371373
• a(n) is the index where A387090(n) appears in A386482.at n=42A386484
