Alex-20s: contains ~1.7M general inorganic materials curated from the Alexandria database, with energy above the convex hull less than 0.1 eV/atom and no more than 20 Wyckoff sites in the conventional cell.
The Alex-20s dataset differs from Alex-20 in that it restricts structures to those containing no more than 20 Wyckoff sites in the conventional cell, while Alex-20 limits the total number of atoms to 20 in the unit cell.
