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). |

COMMENT
|
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), Nov 03 2009]

Note that for a sequence in which every other term is zero, the OEIS policy is to omit those zeros. So this sequence should probably be entered as 1, 0, -3, 8, -15, -25, 24, ... - njas, Nov 08 2009
