Commentary

Derived from the N=925 record: affine-normalize the 22-point seed to a 22-point exact code in (Z/25)^2, complete it by three points to a saturated 25-point core, apply the GL2(Z/25) coordinate change [[9,4],[2,15]], double by vertical shift 25, then delete a minimum 6-point transversal of the q=140 wraparound defect hypergraph.
