Abstract

fetched live from OpenAlex

Abstract Let g ≥ 2. A real number is said to be g-normal if its base g expansion contains every finite sequence of digits with the expected limiting frequency. Let φ denote Euler’s totient function, let σ be the sum-of-divisors function, and let λ be Carmichael’s lambda-function. We show that if f is any function formed by composing φ, σ, or λ, then the number 0.f(1)f(2)f(3)··· obtained by concatenating the base g digits of successive f -values is g-normal. We also prove the same result if the inputs 1,2,3.... are replaced with the primes 2, 3, 5.... The proof is an adaptation of a method introduced by Copeland and Erdõs in 1946 to prove the 10-normality of 0:235711131719...

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.
