OEIS Sequences

T(n,k)=Number of nXk 0..4 arrays with each element·equal to the number of its horizontal and vertical neighbors equal to 4,2,1,0,3 for x=0,1,2,3,4. A197207

E.g.f. W = W(x,m) satisfies: W = E(x·W,m) where E(x,m) = cn(i·x,m) - i·sn(i·x,m), with sn(x,m) and cn(x,m) being Jacobi elliptic functions, read as an irregular triangle of coefficients T(n,k) of xⁿ*m^k for n>=0 and k=0..[n/2]. A290580
