OEIS Sequences

T(n,k)=Number of (n+2)X(k+2) 0..3 arrays with every 3X3 subblock row and diagonal sum equal to 2 3 4 6 or 7 and every 3X3 column and antidiagonal sum not equal to 2 3 4 6 or 7. A252407

E.g.f.: A(x,y) = exp(-1-y) * ∑_n>=0 (exp(n·x) + y)ⁿ / n!, where A(x,y) = ∑_n>=0 xⁿ/n! * ∑_k=0..n T(n,k)*y^k, as a triangle of coefficients T(n,k) read by rows. A326600
