Abstract

fetched live from OpenAlex

<p>This paper studies the Pell-Narayana sequence modulo <span class="math inline">\(m\)</span>. It starts by defining the Pell-Narayana numbers and examining their combinatorial relationships with well-known sequences and functions, including Eulerian, Catalan, and Delannoy numbers. Building on this, the concept of a Pell-Narayana orbit is introduced for a 2-generator group with generating pair <span class="math inline">\((x, y) \in G\)</span>, which allows the analysis of the periods of these orbits. The results include explicit calculations of the Pell-Narayana periods for polyhedral and binary polyhedral groups, depending on the choice of generating pair <span class="math inline">\((x, y)\)</span>, along with a discussion of their properties. Furthermore, the paper determines the periodic lengths of Pell-Narayana orbits for the groups <span class="math inline">\(Q_8, Q_8 \times \mathbb{Z}_{2m},\)</span> and <span class="math inline">\(Q_8 \times_\varphi \mathbb{Z}_{2m}\)</span> for all <span class="math inline">\(m \geq 3\)</span>.</p>

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.
