Driving the weight system for the power series coefficients [math]\displaystyle{ h_n }[/math] of the HOMFLY polynomial. i.e. [math]\displaystyle{ W_{h_n} }[/math] of any chord diagram is [math]\displaystyle{ W_{h_n} }[/math] of the diagram with a chord replaced by a bridge [math]\displaystyle{ - N \times W_{h_n} }[/math] with the same chord deleted; [math]\displaystyle{ W_{h_n}(O^k) = N^{k-1} }[/math].
