%N Triangle of denominators of the cube of a certain lower triangular matrix.
%C The triangle of the corresponding numerators is A119935.
%C See a comment under A119935 on the relation to the triangle A027447.
%H W. Lang: <a href="http://www.itp.kit.edu/~wl/EISpub/A119932.text">First ten rows and rationals.</a>
%F a(i,j)= denominator(r(i,j)) with r(i,j):=(A^3)[i,j], where the lower triangular matrix A has elements a[i,j] = 1/i if j<=i, 0 if j>i.
%Y a(i, j)=1/A002024(i, j), i>=1, j<=i.
%Y Row sums give A119933. Row sums of the triangle of rationals are identical 1.
