New families of double hypergeometric series for constants involving $\frac{1}{\pi^2}$
Bibliographic record
Abstract
We apply a Fourier--Legendre-based technique recently introduced by Campbell et al. in [J. Math. Anal. Appl. 479 (2019), 90--121] to prove new rational double hypergeometric series formulas for expressions involving $\frac{1}{\pi^2}$, especially the constant $\frac{\zeta(3)}{\pi^2}$, which is of number-theoretic interest. The techniques given in this article, applied in conjunction with Bonnet's recursion formula, give us a powerful tool for evaluating double hypergeometric sums containing products of binomial coefficients, and give us many new transformation formulas for double hypergeometric series. The double series considered in this article may be expressed as single sums involving the moments of elliptic-type integrals which have no known symbolic form, as is the case with the inner sum that we obtain by reversing the order of summation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
