Modular and distributive lattices, without vertical sums and 2-sums

The data contains exhaustive listings of nonisomorphic modular lattices (4-35 elements) and distributive lattices (4-60 elements), except for vertical sums and 2-sums. The lattices are stored in digraph6 format and compressed with xz. More details in file 00README.txt. The arXiv manuscript describes how the data were created. Program code is available at .本数据包含非同构模格（nonisomorphic modular lattices，4-35个元素）和分配格（distributive lattices，4-60个元素）的详尽列表，但不包括垂直和（vertical sums）与2-和（2-sums）。这些格以digraph6格式存储，并使用xz压缩。更多细节见文件00README.txt。arXiv预印本手稿描述了数据的生成方式。程序代码可在获取。
