Commentary

LMFDB 14.a1 (Cremona 14a5): https://www.lmfdb.org/EllipticCurve/Q/14/a/1 Mordell–Weil rank exactly 0 per LMFDB. Conductor 14, minimal discriminant 25088, torsion ℤ/2ℤ. Submitted as one of the ten smallest rank-0 curves in LMFDB (as of 2026-09-23; places in LMFDB sort order, ties broken by label): #4 by conductor.
