OEIS Sequences

a(0) = 1 by convention; for n>0, a(n) is the number of points in the n-th figure shown in A255011 (meaning the figure with 4n points on the perimeter). A331449

Triangle read by rows: T(n,m) (n >= m >= 1) = number of vertices formed by drawing the lines connecting any two of the 2*(m+n) perimeter points of an m X n grid of squares. A331453

Sequence is defined by property that (a0,a1,a2,a3,...) = binomial transform of (a0,a0,a0,a1,a1,a1,a2,a2,a2,a3,a3,a3,...). A51164

a(n) = F(n+4) * F(n+1) - 4 * (-1)ⁿ where F(n) = A000045(n) are the Fibonacci numbers. A341208

Number of mobiles (circular rooted trees) with n nodes and 3 leaves. A55341

Column 4 of A060244. A291589

Numbers k such that 131·2^k+1 is prime. A32415

Triangle T(n,k) = coefficient of xⁿ in expansion of ((1-sqrt(1-4·x))/((1-x)*2))^k = sum(n>=k, T(n,k) * xⁿ). A200965

Absolute value of the minimum coefficient of (1 - x)³ * (1 - x²)³ * (1 - x³)³ * ... * (1 - xⁿ)³. A380517

Numbers k such that sum of digits of k-th prime equals sum of digits of k. A33549
