Setup

Start by downloading either the file KnotTheory.tar.gz or the file KnotTheory.zip (around 1MB each), and unpack either one. This will create a subdirectory KnotTheory/ in your current working directory. This done, no installation is required (though you may wish to check out Further Data Files below). Start Mathematica and you're ready to go:

In[1]:= << KnotTheory`

Loading KnotTheory` (version of August 19, 2005, 13:11:25)...

Let us check that everything is working well:

In[2]:= Alexander[Knot[6, 2]][t]

Out[2]= $-t^{2}+3t-3+{\frac {3}{t}}-{\frac {1}{t^{2}}}$
