The first way has A124736 as row lengths and A124748 as row sums; the second has A001792 as row lengths and A001787 as row sums. %C A124735 This sequence includes every finite sequence of nonnegative integers. %F A124735 a(n) = A124734(n) - 1. %e A124735 The table starts: %e A124735 0 %e A124735 1; 0 0 %e A124735 2; 0 1; 1 0; 0 0 0 %Y A124735 Cf.
