Understanding Folgezettel requires prior knowledge of Luhmann's Zettelkasten method, the notion of partially ordered sets, and the definition of lexicographic order.
**Claim**:
Folgezettel IDs can be formalized as elements of a partially ordered set \( (F, \preceq_F) \), where \( F \) consists of structured strings like \( v_1|i_1v_2|i_2\cdots|i_kv_k \).
**Support**:
Defined via inductive construction over \( \Sigma = \mathbb{N} \cup \{., |_n\} \). Lexicographic order \( \prec \) ensures hierarchy: \( 1.2 \prec 1.3 \prec 1.3.1 \).
**Rebuttal**:
Non-falsifiable claim: "Inductive definition guarantees hierarchy" assumes consistent adherence to numbering rules.
The result is a sequence of notes (Zettel) or wiki pages that appear in the federated wiki as a Lineup. example
