  "commentary": "Fiber t = 6150/32059 of a rank-17 elliptic fibration of Elkies' K3 surface (arXiv:2608.25406): the 2-neighbour fibration that also carries NDElkies' #404 and wgxli's #393. Found by a Mestre-Nagao sieve over t = a/b, re-scored at 2^20, followed by an iterated 'bootstrap' 2-covering point search (fake 2-descent over cosets of the growing known lattice, minimal reduced quartic models, ratpoints). Basis LLL-reduced with respect to the canonical height. The 29 points are certified independent by the F2-rank of their images under the 2-descent map at the good primes.",
