Curve and 13 rational points reproduced from the Layr Labs / Yukon Elliptic Rank Challenge (October 2026), file `submission/board/2x2-13.ec`.
Original discovery and credit belong to the Yukon challenge participant who constructed this curve; the ICARM submitter is not the discoverer.

Torsion Z/2Z x Z/2Z, rank lower bound 13 (13 supplied rational points). Naive height approximately 317.0210, improving on the October 15 ICARM snapshot's previous minimum of approximately 336.9906 for this torsion group and rank threshold.
