%N A130093 A051731 * a lower triangular matrix with A036987 on the main diagonal 
               and the rest zeros.
%C A130093 Right border = A036987, the Fredholm-Rueppel sequence, (1, 1, 0, 1, 0, 
               0, 0, 1, 0,...). Row sums = the ruler function, A001511: (1, 2, 1,

%C A130093 Contribution from Gary W. Adamson (qntmpkt(AT)yahoo.com), Oct 21 2009: 
               (Start)
%C A130093 A130093 also = A047999 (Sierpinski's gasket) * A036987 diagonalized, 
               as
%C A130093 infinite lower triangular matrices.
%C A130093 Eigensequence of A130093 = A001511, (same sequence as row sums). (End)
