Abstract

fetched live from OpenAlex

Abstract In this manuscript, we generalize Lewis’s result about a central series associated with the vanishing off subgroup. We write $V_{1}=V(G)$ for the vanishing off subgroup of $G$ , and $V_{i}=[V_{i-1},G]$ for the terms in this central series. Lewis proved that there exists a positive integer $n$ such that if $V_{3}<G_{3}$ , then $|G\,:\,V_{1}|=|G^{\prime }\,:\,V_{2}|^{2}=p^{2n}$ . Let $D_{3}/V_{3}=C_{G/V_{3}}(G^{\prime }/V_{3})$ . He also showed that if $V_{3}<G_{3}$ , then either $|G\,:\,D_{3}|=p^{n}$ or $D_{3}=V_{1}$ . We show that if $V_{i}<G_{i}$ for $i\geqslant 4$ , where $G_{i}$ is the $i$ -th term in the lower central series of $G$ , then $|G_{i-1}\,:\,V_{i-1}|=|G\,:\,D_{3}|$ .

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.
