: As we have already mentioned, since the expressions showing up in the characterizations of the transition lines are long, we use the SageMath package for our symbolic computation. In fact the expressions are so long that evaluating those expressions using the Sage interpreter is very time-consuming. Therefore, we use the code generation facilities of the <tt>sympy</tt> library to generate C code so that we can do the numerical computation in C. We have included the file <tt>potts-numerics-1.0</tt> in the Electronic Supplemental Material 2 (ESM) which contains the code and further information on how to use it. With this package you can, for example, create high-resolution plots of the functions involved in the computation of the lines BU, TPE and ACE, or generate bifurcation set slices and Maxwell set slices.
