This is a SageMath package for studying flexible and rigid labelings of graphs. It implements the concepts described in the papers Graphs with Flexible Labelings (doi:10.1007/s00454-018-0026-9), Graphs with Flexible Labelings allowing Injective Realizations (doi:10.1016/j.disc.2019.111713) and On the Classification of Motions of Paradoxically Movable Graphs (doi:10.20382/jocg.v11i1a22) by Georg Grasegger, Jan Legerský and Josef Schicho, and in the doctoral thesis Flexible and Rigid Labelings of Graphs by Jan Legerský (available here). The package is described in FlexRiLoG – A SageMath Package for Motions of Graphs (doi: 10.1007/978-3-030-52200-1_44) by Georg Grasegger and Jan Legerský. The latest version of the code can be found in the G...
