FlexRiLoG - constructing flexible realizations via edge colorings

Abstract

FlexRiLoG is a SageMath package which provides tools for studying paradoxical flexibility of bar-joint frameworks in the plane. This is achieved using NAC-colorings: edge colorings by two colors such that every cycle is either monochromatic or contains at least two edges of each color. The functionality of the package shall be presented including generalizations to frameworks that consist of triangles and parallelograms and/or have a symmetry.
