We describe a new feature of pysecdec, a toolbox for
parametric and loop integrals in the context of dimensional regularization.
Due to its modular structure, most algorithms implemented in pysecdec's
algebraic preprocessing can be called in user-defined codes. Therefore,
pysecdec can be applied in contexts beyond numerical evaluation of
parameter integrals. We show how the symmetry finder in
pysecdec can be used to identify matroid symmetries of anisomorphic graphs.
We further discuss its use within loopedia, a database for loop integrals.
