Appears in sequences

• Sequence composed of consecutive square matrices A(d) with dimension d=1,2,3,... Matrix elements are arranged by increasing row index i, and, within fixed i, by increasing column index j. Each block A(d) is related to the inverse of a class of integer Vandermonde matrices.at n=63A347781
• G.f.: 1/(1 + (x+x^2 + x)/(1 + (x+x^2 + x^2)/(1 + (x+x^2 + x^3)/(1 + (x+x^2 + x^4)/(1 + ...))))), a continued fraction.at n=12A352234
• Expansion of Sum_{k>0} x^(4*k)/(1+x^k)^4.at n=32A363616
• Expansion of e.g.f. exp(exp(x) - exp(3*x)).at n=6A368017
