Abstract

fetched live from OpenAlex

Abstract An oriented octahedral design of order v , or OCT( v ), is a decomposition of all oriented triples on v points into oriented octahedra. Hanani [H. Hanani, Decomposition of hypergraphs into octahedra, Second International Conference on Combinatorial Mathematics (New York, 1978), Annals of the New York Academy of Sciences, 319, New York Academy of Science, New York, 1979, pp. 260–264.] settled the existence of these designs in the unoriented case. We show that an OCT( v ) exists if and only if v ≡1, 2, 6 (mod 8) (the admissible numbers), and moreover the constructed OCT( v ) are unsplit, i.e. their octahedra cannot be paired into mirror images. We show that an OCT( v ) with a subdesign OCT( U ) exists if and only if v and u are admissible and v ≥ u +4. © 2010 Wiley Periodicals, Inc. J Combin Designs 18:319–327, 2010

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
