 OFFSET 0,3 COMMENTS The numerators are given in A164658. See the W. Lang link in A164658 for this table and the rational table A164658/A164659. LINKS FORMULA a(n,m) = denominator(b(n,m)), with int(T(n,x),x)= sum(b(n,m)*x^m,m=1..n+1), n>=0, where T(n,x) are Chebyshevs polynomials of the first kind. EXAMPLE Rational table A164658(n,m)/a(n,m) = [1], [0, 1/2], [-1, 0, 2/3], [0, -3/2, 0, 1], [1, 0, -8/3, 0, 8/5],... CROSSREFS Row sums of this triangle give A164663. Row sums of rational triangle A164658/A164659 are given in A164660/A164661.
