%N Triangle read by rows, descending antidiagonals of a (1, 3, 5, ...) * (1, 4, 16, ...) multiplication table.
%C Binary representation of all terms ends in an even number of zeros (cf. A003159).
%F Triangle read by rows, descending antidiagonals of a (1, 3, 5, ...) * (1, 4, 16, ...) multiplication table.
%e Given the multiplication table (1, 3, 5, ...) * (1, 4, 16, ...); i.e., odd numbers as column headings, powers of 4 along the left border:
%e 1, 3, 5, 7, ...
%e 4, 12, 20, 28, ...
%e 16, 48, 80, 112, ...
%e 64, 192, 320, 448, ...
%e ...
%e Rows of the triangle = descending antidiagonals of the array, getting:
%e 1;
%e 3, 4;
