OEIS Sequences

Triangle read by rows giving the coefficients of formulas generating each variety of S1(n,k) (unsigned Stirling numbers of first kind). The p-th row (p>=1) contains T(i,p) for i=1 to 2·p, where T(i,p) satisfies ∑_i=1..2·p T(i,p) * C(n,i). A94216

Number of Hamiltonian paths in the graph on n vertices {1,...,n}, with i adjacent to j iff |i-j| <= 2. A69241

Ceiling(4/3*π*n³). A135973
