OEIS Sequences

Values of n such that L(9) and N(9) are both prime, where L(k) = (n²+n+1)*2^2·k + (2·n+1)*2^k + 1, N(k) = (n²+n+1)*2^k + n. A226929

Triangle T(n, k) = ∏_j=1..k ∏_i=0..j-1 ( 1 - (n-k+1)*(3·i-2) ) with T(n, 0) = 1 and T(n, n) = n!, read by rows. A156730

Irregular triangle read by rows: mean version of Girard-Waring formula A210258, for m = 5 data values. A288207

Riordan array (1-4x, x(1-x)³). A119305

Difference between sums of quadratic residues and non-residues modulo n (residues are not necessarily coprime to n). A255644

Expansion of ∏_m>=1 (1-m·q^m)²⁰. A22680
