"""C3 (claim [2]) of 'Optimal Transport with Symmetry Groups' (OpenReview C4JJrPSwpy): the
priority/novelty assertion "Method is the FIRST to systematically incorporate finite group
symmetries into optimal transport."

The judge marked this inconclusive: it is a novelty assertion requiring a literature audit. We
perform a primary-source prior-art audit. The audit records, for each prior work, its public
date, venue, and the specific way it incorporates finite group symmetries into optimal transport
/ Wasserstein distances. The paper (OpenReview C4JJrPSwpy) is an ICML-2026 submission (public
~Jan 2026); any work incorporating finite-group symmetry into OT that is public before that date
is prior art that FALSIFIES the unqualified 'first' claim.
