OEIS Sequences

a(n) = (n+1)*(2-n)/2. A80956

Triangle, read by rows of n² terms, where row n equals the coefficients in the series reversion of the function G(y,n)-1 such that: y = ∑_m>=1 1/G(y,n)^2·n*m * ∏_k=1..m (1 - 1/G(y,n)^2·k-1). A214690

G.f. satisfies: A(x) = 1/(1 + x·A(x⁸)) and also the continued fraction: 1 + x·A(x⁹) = [1; 1/x, 1/x⁸, 1/x⁶⁴, 1/x⁵¹², ..., 1/x^{8^(n-1}), ...]. A101918
