OEIS Sequences

Triangle read by rows: terms T(n,k) of a binomial decomposition of n as Sum(k=0..n)T(n,k). A244143

The result of the integration Integral_t=0..oo -ρ*exp(-ρ*s·t)*t^j*s·log(1+t) dt can be written as (F(u,j)*exp(u)*Ei(1,u) + G(u,j))/u^j, where ρ>0, s>0, and u=ρ*s. Sequence is the regular triangle corresponding to G(u,j). A121922
