Lists of finite lattices (modular, semimodular, graded and geometric)

Listings of finite lattices in four families, stored in xz-compressed digraph6 format: (1) Modular vertically indecomposable lattices up to 30 elements (2) Duals of semimodular vertically indecomposable lattices up to 25 elements (3) Graded vertically indecomposable lattices up to 20 elements. (For 21 elements see a separate repository.) (4) Duals of geometric lattices up to 34 elements For more details see https://arxiv.org/abs/1708.03750
