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,7). The p-th row (p>=1) contains a(i,p) for i=1 to 7·p-6, where a(i,p) satisfies ∑_i=1..n C(i+6,7)^p = 8·C(n+7,8) * ∑_i=1..7·p-6 a(i,p) * C(n-1,i-1)/(i+7). A87111

a(n) = ((n-th prime)⁶-(n-th prime))/2. A138440

Cubes written in base 9. A4639

Triangle read by rows: T(n,k) = (n+1,k)-th element of (M⁷-M)/6, where M is the infinite lower Pascal's triangle matrix, 1<=k<=n. A96041

Numbers k with property that 19·k + {2,4,8,10} are two pairs of consecutive twin primes. A152926

Numbers of the form k*(k⁵ +- 1)/2. A361263

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
