- Click “Evaluate” on the SageMathCell below to check out the hyperplane arrangement $\mathcal{H}(3)$. The hyperplanes $H_{1,2}, H_{1,3}, H_{2,3}$ have been colored red, green, and blue, respectively. The plane $x+y+z=0$ is also included and is colored purple. In addition, I’ve included the vector $(1,2,3)$ in orange to illustrate where the chamber corresponding to the intersection of the three positive half-spaces lies. After evaluating the cell, it may take a few seconds for the image to render. You can click and drag the image to move it around and you can zoom in and out.
