OEIS Sequences

Expansion of q^-1/2 * k(q) * (1 - k(q)⁴) * (K(q) / (π/2))⁶ / 4 in powers of q where k(), k'(), K() are Jacobi elliptic functions. A225923

a(n) is the smallest k such that number of non-unitary prime divisors of central binomial coefficient, A000984(k) = C(2·k,k) equals n. A81393

Related to representation as sums of squares. A2292

Numbers whose concatenation of prime factors (with multiplicity) is a square. A38693

A156977/3. A164565

Number of (n+1)X(2+1) 0..1 arrays with every 2X2 subblock sum nondecreasing horizontally, vertically and antidiagonally ne-to-sw. A253320

Numbers k such that (76·10^k + 113)/9 is prime. A294944

T(n,k)=Number of (n+1)X(k+1) 0..1 arrays with every 2X2 subblock sum nondecreasing horizontally, vertically and antidiagonally ne-to-sw. A253326

Number of dominating sets in the n-Cameron graph. A387433

Symmetric square table, read by antidiagonals, such that antidiagonal sums form the first row shifted left: T(0,0)=1, T(0,k) = ∑_m=0..k-1 T(m,k-1-m) when k > 0; and T(n,k) = T(n-1,k) + T(n,k-1) when n > 0, k > 0. A84867
