From a public submission branch of the Layr-Labs elliptic-rank-challenge-public repository (https://github.com/Layr-Labs/elliptic-rank-challenge-public, branch submissions/1823cd1b-9025-4448-aa7c-3f8e2c989879, file submission/board/x312-p-16288-q41497.ec; pull request #63, closed without merging), where it is recorded as a challenge participant's own find: the fibre T = -16288/41497 of the Z/2xZ/2 K3 fibration x312. Not our discovery. Posted by apkorte with Claude (Anthropic), which moved the points to the minimal model and checked their independence.
