Abstract

fetched live from OpenAlex

In a recent report, Gulliver and Speidel showed that complete sets of aperiodic and - in some cases periodic - necklaces can be generated for arbitrary lengths as fixed-length subsets of variable-length T-codes. The T-codes to which they applied this observation were specifically T-codes constructed by systematic T-augmentation, that is by T-augmentation sequences in which each T-expansion parameter is 1 (simple T-augmentation) and where the T-codes A_{(p1,p2,pi)} at each Taugmentation level i do not contain any codewords shorter than pi (strictly minimal T-augmentation). This present paper generalizes their result to arbitrary T-codes and formalizes their earlier result as a special case of the general result.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
