Invariants are essential for classifying mathematical objects up to a group of transformations. This talk will review several constructions of rational invariants where a section to the orbits is an essential ingredient for tractable computations. We will start with a general construction to obtain a generating set for the field of invariants. The output of the algorithm further provides rewrite r
