These are the supplementary files for the paper “New Ramsey Multiplicity Bounds” by Parczyk, Pokutta, Spiegel, and Szabo. Upper bounds. All graphs are described through their graph6 string. A full description of how to derive this description is included in the file graph6_description.txt. All small constructions are stated in the paper and the larger constructions are contained in the archive graphs.zip. Lower bounds. We supply a certificate for all lower bounds stated in our paper in the archive graphs.zip that can be verified using flagmatic. At the time of writing, a version of flagmatic can be found at https://github.com/jsliacan/flagmatic. Since this version relies on some no longer maintained software, we found it best to run it in docker container and have supplied the Dockerfile as well.
