The Relations
The Reidemeister Move R3
The picture (with three sides of the shielding removed) is
In formulas, this is

Linearized and written in functional form, this becomes

The Syzygies
The "B around B" Syzygy

The functional form of this syzygy is

A Mathematica Verification
The following simulated Mathematica session proves that for our single relation and single syzygy, . Copy paste it into a live Mathematica session to see that it's right!

Here Goes Something New(?)
The first thing to notice is that the relation holds for and so we have another version:
|
|
|
|
This is probably a completely trivial remark, and it is also trivial to see that mathematica will deal with this in the same way as for so I won't verify that .
What I will do now is linearize and write down in functional form the relation R2
