Elements (20)

0, 5, 25, 30, 289, 290, 294, 295, 314, 315, 319, 320, 432, 434, 437, 439, 457, 459, 462, 464

Commentary

Same fixed 20-point digit family extracted from N=645: N=5q and (u,v) -> uq+v. Since all v lie in [0,32], any forbidden relation has |V|<=128; q>=129 forces V=0, and the finite digit template has no nontrivial relation with U=0 mod 5.
