%N A131386 The sequence is generated by a triangle, generated by Boubaker polynomials 
               as follows: B_0(x)=1, B_1(x)=x, B_2(x)=x^2+2, B_n(x)=x*B_{n-1}(x)-B_{n-2}(x).
%C A131386 The sequence appears to be unrelated to coefficients of the polynomials; 
               I do not understand the definition. [R. J. Mathar, mathar(AT)strw.leidenuniv.nl),
