Jun 12, 2017 at 22:45 comment added Zuriel @Suki, every box is as is shown in the graph near the bottom of Page 4. Consider the first box as an example. If it has $2$ crossings and the top colour is $(x_1,x_2)^T$, the bottom colour satisfies $(y_1,y_2)^T=B(x_1,x_2)^T$. Similarly if it has $2n$ crossings, we have $(y_1,y_2)^T=B^n(x_1,x_2)^T$.
Jun 12, 2017 at 22:26 comment added Suki Thanks. One more question. I would like to know what the presentation matrix of a two strand braid coloured with an alexander quandle look like? I don't get how the matrix B from corollary 5.2 is associated with the boxes.
