The Jones Polynomial

The knots 6_1 and 9_46 have the same Alexander polynomial. Their Jones polynomials are different, though:

$In[1]:=</tt><code>Jones[Knot[6,2]][q]</code>Out[1]=</tt><math>q-1+{\frac {2}{q}}-{\frac {2}{q^{2}}}+{\frac {2}{q^{3}}}-{\frac {2}{q^{4}}}+{\frac {1}{q^{5}}}$

Again:

In[1]:= Jones[Knot[6, 1]][q]

Out[1]=

$q^{2}-q+2-{\frac {2}{q}}+{\frac {1}{q^{2}}}-{\frac {1}{q^{3}}}+{\frac {1}{q^{4}}}$

$In[2]:=</tt><code>Jones[Knot[9,46]][q]</code>Out[2]=</tt><math>2-{\frac {1}{q}}+{\frac {1}{q^{2}}}-{\frac {2}{q^{3}}}+{\frac {1}{q^{4}}}-{\frac {1}{q^{5}}}+{\frac {1}{q^{6}}}$

Again:

In[2]:= Jones[Knot[6, 1]][q]

Out[2]=

$2-{\frac {1}{q}}+{\frac {1}{q^{2}}}-{\frac {2}{q^{3}}}+{\frac {1}{q^{4}}}-{\frac {1}{q^{5}}}+{\frac {1}{q^{6}}}$
