OEIS Sequences

This table shows the coefficients of combinatorial formulas needed for generating the sequential sums of p-th powers of binomial coefficients C(n,6). The p-th row (p>=1) contains a(i,p) for i=1 to 6·p-5, where a(i,p) satisfies ∑_i=1..n C(i+5,6)^p = 7·C(n+6,7) * ∑_i=1..6·p-5 a(i,p) * C(n-1,i-1)/(i+6). A87110

Number of right triangles on a (n+1)X6 grid. A189810

a(n) = ∑_{-n<i<n, -n<j<n, gcd{i,j}=3} (n-|i|)*(n-|j|). A331774

Irregular triangle read by rows. Row n gives the coefficients of the polynomial multiplying the exponential function in the e.g.f. of the (n+1)-th diagonal sequences of triangle A008459 (Pascal squares). T(n,k) for n >= 0 and k = 0..2·n. A290310
