OEIS Sequences

Number A(n,k) of paths starting at {n}^k to a border position where one component equals 0 using steps that decrement one component by 1; square array A(n,k), n>=0, k>=0, read by antidiagonals. A210472

a(n) = ∑_k=1..n k·k!*C(n,k). A93964

a(1) = 8, a(n) = smallest number > a(n-1) such that the concatenation of a(n-1) and a(n) is a square. A265149

a(n) = 1 + ∑_i=1..n ∑_j=1..n i^j. A124405

Triangle T(n,k) read by rows, where o.g.f. for T(n,k) is n!*∑_k=0..n (1+x)^n-k/k!. A73474
