A370049 - cp's OEIS frontend

A370049 Square array A(n, k), n, k >= 0, read by antidiagonals; for any n and k >= 0 with respective binary expansions Sum_{i > 0} b_i2^(i-1) and Sum_{i > 0} c_i2^(i-1), the binary expansion of A(n, k) is Sum_{i > 0} d_i2^(i-1) with d_i = (Sum_{k divides i} b_kc_{i/k}) mod 2 for any i > 0.
