2026-09-16 11:23 bmatschke interactive tags: Sheffer sequence. a tag is a family of tables, and these are the members of one. numberdb-data#112 asked for it; the membership is decided by the generating function each table gives, not by its title. current reviewed

2026-09-01 22:15 bmatschke attach each link to the name it follows, so the name is the link
2026-09-01 22:12 bmatschke link each family the first time it is named, where the corpus holds a table of it
