Congruence properties modulo powers of 2 for partition pairs into distinct parts
Bibliographic record
Abstract
Let $Q(n)$ denote the number of partitions of $n$ into distinct parts. In 1997, Gordon and Ono proved that almost all values of $Q(n)$ are divisible by $2^m$ with any fixed positive integer $m$. Let $Q_2(n)$ denote the number of partition pairs of $n$ into distinct parts. A result derived by Ray and Barman reveals that almost all values of $Q_2(n)$ are also divisible by $2^m$ with any fixed positive integer $m$. Quite recently, the author derived several internal congruences and congruences modulo powers of $2$ satisfied by $Q(n)$. In this paper, we prove some internal congruences and congruences modulo powers of 2 for $Q_2(n)$. Moreover, we prove an infinite family of congruence relations modulo $4$ and dozens of congruence relations modulo powers of $2$ enjoyed by $Q_2(n)$. Finally, we pose two conjectures on congruence properties modulo powers of $2$ for $Q_2(n)$.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
