Graded Ring Database

The Graded Ring Database (GRDB) is an online resource for researchers in geometry and combinatorics that combines several major classifications in those areas. It contains large databases of geometric data, including the classification of all toric canonical 3-folds, Calabi–Yau 3-fold hypersurfaces, and candidate Hilbert series for Fano 4- and 5-folds. It also contains combinatorial data such as the classification of LDP polygons and the smooth Fano polytopes. These classifications can be queried using the forms on the website, or via an easy-to-use XML interface.
