Sum of a(n) terms of 1/k^5/6 first exceeds n. A56181

A(n,k) = ∑_{h=0..n-1, m=0..k} A(h,m) for n >= 1 and k >= 1, with A(n,0) = 1 for n >= 0 and A(0,k) = 0 for k >= 1; square array A, read by descending antidiagonals. A50143

Irregular array read by rows: row k (k>=1) contains k² numbers, formed by filling in a k X k square by rows so entries in all rows, columns, diagonals, antidiagonals are distinct, and then reading that square across rows. A308880
