We compute the (or quantum ) invariant using the normalization and formulas of [Khovanov], which in itself follows [Kuperberg]:

(For In[1] see Setup)


As an example, let us check that the knots 10_22 and 10_35 have the same Jones polynomial but different invariants:



The invariant attains values on the knots and links known to KnotTheory:
